DIY Plastic Bumper Repair – How To Repair Cracks or Torn In Car Bumper Covers – Two-Sided


– Hey there, YouTube, this is Donnie, and in today’s video, I’m gonna show you how to fix a rip or tear
in a plastic bumper cover. So if you’ve got a rip or
tear in your bumper cover, don’t throw it away,
because after this video, you’ll know how to repair it yourself. (energetic electronic music) Now I just cut a piece
of a bumper cover off to make it easy to demonstrate,
and on this tear or rip, it’s gonna be on the edge,
so you can see that it’s, you can see the edge here,
I did that on purpose so that I can show you
how to dish this out. Now, the tear can be anywhere. It can be on the edge,
it can be in the center, it can be basically anywhere. The same repair method that
I’m gonna show you today will work to repair a crack
or rip in a bumper cover. Now, with any auto body
repair you’re doing, it’s always important to
wash and clean it first to remove the contaminants. I’ve already did that, so we’ll go ahead and get started repairing this. Okay, first I’m going
to grind this backside. I’ve got some 50 grit on a Roll Lock Disc. I’m basically gonna rough
this up, so that adhesives and the reinforced fiber
that I’m gonna put on here will hold, will adhere well. So I’m gonna go ahead and do that. You don’t have to dish the backside out like we’re going to the front
side, just rough up an area, probably a couple inches
larger than the repair, so that gives you plenty of repair area. (drill buzzing) (electronic music) Well, we tried to work
it on the edge here. That wasn’t working too good so I had to get my helper here to help me out, kind of hold it in place. So we’ll continue sanding
and dishing this out with this 50 grit. (syncopated electronic music) (drill buzzing) Alright, I’ve got it ground, I’ve got it roughed up in
the back with some 50 grit. I dished it out in the front and it may be hard to see on camera. See how thick this is up here
and it gets a lot thinner and at this point right
here it’s pretty thin. And then it starts to get thicker again. And that’s what I’m talking
about dishing that out, wherever this has some room
for the adhesive to fill in. So dish the front side out like that where it’s thick, thin and thick, rough the backside and
then you want to make sure there’s a few little loose things on here, you should get all those off. You might need to get a razor blade and cut any of those loose
pieces of plastic off before you start using adhesives. (electronic music) Now there’s one last
thing that you want to do is get some 80 grit and
go ahead and sand this and help feather this out. So we’re gonna sand this out some, and I’m wanting to feather
each layer of coating out. Now I’m gonna use a piece
of 180 to go over that, and these are little blocks that 3M has kind of works like a paint
stick for this hook it paper. Velcro sticks to it. I’m gonna go over this just
to minimize the scratches, and to help feather those layers of coating a little bet better. I’ll go over the whole thing. This also makes sure that
any loose plastic is removed. (electronic music) Now on the backside, I’m just gonna go over it with some 80, just to make sure that any loose pieces of plastic, like this right here, I’ve
got a loose piece there, little bit and pull it off of there. And you want to go ahead
and look at it at this point and if there is any
loose pieces of plastic you want to get those off there. Now with any type of plastic repair, now you can blow it off
with compressed air. I’m gonna use a wipe ball to wipe it down, but you do not want to
use any type of solvents because that can absorb into this plastic and give you some problems later. I’m gonna go ahead and clean it off. (electronic music) Now that it’s good and clean, a very important step
is to be sure and use this plastic adhesion promoter. The adhesives may not adhere
properly if you don’t use this and that’s something that you don’t want. You want everything to stick really good. So we’re just gonna put just a light coat. I’m gonna put it on the front and the back anywhere I’m gonna put this adhesive. You don’t want to put it on
too thick, just a light coat. Now you also want to make
sure that that is dry. You don’t want to put your
adhesive while that’s wet. That will cause problems. So we’re gonna let that sit anywhere from five to ten minutes. If it’s cooler in the shop,
you may wait even longer. Okay we’ve allowed this to dry, and what I’m gonna do now, is I’m gonna put some
tape on the front side just to keep the adhesive
from coming through whenever we repair the backside. And if it was misaligned or something this would help keep it
in alignment as well. Okay, now we can flip it around, and do the backside repair. And again if I was doing
this on the bumper, I’d probably try to position the bumper where it’s laying flat. It makes it easier to put the adhesive. You can put it on at any angle, but I’m gonna put it on so you
can see it better like this. Before we get the adhesive out, I’m gonna cut a piece of
this fiber reinforcement that will fit over this and extend it oh about an inch or so. So I’m gonna pre-cut this, So something like that will be fine. We’ll go out past the repair, so we’ve got that ready
and we’ll lay it right here so it will be ready. Now after you’re done using
this each time, this tip just leave it on there
because that seals it off, the adhesive dry’s in this tip and makes a really good
seal and keeps this from hardening up. So after the last time
I left that on there and now I’m gonna take it off, then you just put the
cartridge into the gun like that, and before we put the tip on, I want to shoot a little out just to make sure it’s
coming out of both sides the way it should. Okay, it’s coming out fine, so I’m gonna put the tip on now I’m just gonna apply
some of this adhesive to the repair area. And for the backside, we’re gonna use, this is a EZ Sand Rigid, that’s what’s used for the backside. And on the front side, we’ll
use Flexible Parts Repair. Now I’m just gonna spread this out, and now you can set your
reinforcement on there. Push it down in there so that
you make sure that its covered and then I’m gonna put a
little bit more on top. You want to make sure the reinforcement’s covered well and there’s
no edges sticking out, and I can kind of push
it down to make sure. Now what I have is adhesive, and it extends past the damaged area, at least an inch or a little bit more. And we have the adhesive
that’s gonna hold that on. Now the backside, that’s
all you have to do. There’s really no need
to sand it or anything because you’re not going
to see the backside when you’re done. We’re gonna let that set up a little bit, and then what we’ll do
is we’ll flip it around and then show you how to
finish out the front side. But before we pull that tape off, we’re just gonna set
it here and allow that to dry for a little bit. So now you just flip it around and basically do a one-sided repair. I’m gonna get the flexible adhesive, and I’m gonna push it
over and do a tight coat, followed by a fill coat to
help fill in this low area, and then I’ll block sand it
out with 80 followed by 180. This is basically now
just a one-sided repair just like we did this one. I’ll put a link to the video to this one if you haven’t seen the one-sided repair you can just click right
here and you can watch it. And it’s basically the steps to do from here, to take it from this, to this. Then once it’s finished
out, it’ll be like this you’ll have it ready for prime,
block and ready for paint. So on this little sample piece, we’ve done a tab repair,
we had a tab broke off, you know, how do you repair that. And if you didn’t see
the tab repair video, you can click right here and watch that. And then we done a one-sided repair and that’s if you have
damage on the outside but it doesn’t go through, it’s not ripped or tore. You just need to repair the outside. We did the steps for that. And of course this, the steps from here will just follow the
exact same steps as this. Now, I’m not gonna go through and do those steps again,
cause it’s identical to this video here. You basically you put a tight
coat, followed by a fill coat block it out and get
ready for prime and paint. And this of course, is
the two-sided repair where it goes through, you need to reinforce the backside and then basically, you
have a one-sided repair. Hey, that raps up this video, I thank you for taking the
time to watch this video and if you liked it, be sure
and give us a thumbs up. You can go down here and
click the like button and also be sure to
subscribe to this channel. But I appreciate you watching, and we’ll talk to you next time. A little bit bigger,
and we’re gonna grind it to make it the exact same size. Now you want to leave it like that glove, you want it to go over just a little bit, so I’m gonna leave a little bit

  1. It would be a good idea to drill a 6 mm hole at the end of the tear to keep it from going further, since it would suffer some serious vibration under driving conditions!

  2. Good timing on the video, need to fix a bumper on a car I just bought. On a side note, this video is extremely hard to watch with the static background, no need to try and be fancy with the videos. I would rather see you working in a live shop setting like most of your videos before. Just my $.02

  3. Thanks for the feedback. I have been trying a few things, but I've learned that I am not very good at video editing.

  4. sir. I have damaged front plastic bumper on my suzuki mini van, a tear similar on the video you demo'd. I used welded plastic method (60W soldering iron with a small disc on the it's tip). My question is this, sir; Is it necessary to apply first plastic adhesion promoter on the repair area before applying body filler or body filler first before plastic adhesion promoter?

  5. Irregardless of the green screen, this was a very informative video.  Thanks for instruction without the silliness, garage girls or amateurs stuttering, stammering and meandering all over the place for 5 or more minutes to make a 2 minute video.  Very professional.

  6. great video where can i get some of that invisible tape? just kidding. the green screen might not be the best idea but I was still able to see all the steps clearly. thanks for the great videos you do a great job.

  7. Great video, Please can you provide me with appropriate links where i can buy or exact list of all the lubricants used in this video?
