How to fix a bedliner

Well guys, i would kind of like to repair the liner in my truck... I really like it, and id like to keep it looking nice...

Were building a deck, and the other night i went to lowes and bought about 10 bags of sand and brought them home. It was getting dark, so i figured id just leave them in the truck and unload them the next day.

So, going to school the next morning, i was just cruising along and some idiot in a Pontiac in front of me slams on his breaks, for no apparent reason. I stomp on mine and i hear this strange noise in the back of the truck then a bang, and the whole thing jolts. The car than floors it, screeches his tires and is gone. I think he was doing some 0-30 for his friends or something...

The people at lowes didn't put the pallet all the way in the front of the truck. I didn't worry about it, since i was just going a couple miles on really calm roads.

The pallet slid forward about 18 inches, and hit the front of the bed liner. The front of the pallet took on the shape of the liner, and you can see where the bags flew into it.

When i got home, i looked the thing over, and the only damage is two new cracks on the top of the liner. I would like to fix those, along with this little rip that came with the truck when we got it.

Id assume just use a heat gun, but i dont want to mess up the paint, of the nearby window seals. Is there some kind of epoxy/bondo like stuff i could use?? How is this done?? Thanks in advance...

I would try and use two part epoxy that works preaty good, or try and find some one whow has a plastic welder. I do know at one time Harbor freaght sold them and they real easy to use, I have one. They work great.

Lanse, you can use a heat gun in that area if you
are careful, but it looks like the liner may still
have some stress/pressure on it, and that "should"
be relieved first. In the body shops, we have a 2-
part material we use for repairing various
plastics. Some are used on the urethane bumpers,
some are for other plastics. If there is a store
near you who supplies body shops with their repair
materials, go to them. The kit is not cheap, and
looks like you will only sue a small amount. Any
chance there is an autobody repair class in your
high school? if so, talk to the instructor, and
see if he will get a student to fix it. As a last
resort, take it to a body shop, and at least get a
price. I was hoping it was one of the spray in
liners, because it would be an easy repair with
one of the aerosol cans to touch it up... Good
luck, and wish you were closer with some of these
problems, we could give a lot of help to you down
this way.

Allright... Thanks guys

Would this two part epoxy work?

Lanse, I'm afraid it may not bond to the bedliner.
It may also dry to brittle, and just break again.
The product(s) we use is made by 3M.I can't recall
the numbers off hand, as we have several in the
shop. They have different products, for the
various type of "plastics". When you do make the
repair, I'd suggest drilling a very small hole at
the end of each tear/break. this will stop it from
going any further. Actually, it would be a good
idea now, before the repair. It can be 1/16-1/8th
inch. I will try to get by the shop before Monday
if I go in town, and get a number for you. There
are some other suppliers who make a "difficult
plastic repair" product which is kind of a
universal product, and works pretty good, but you
need to stick close to the automotive stuff if
possible.

I can pretty much say for sure that no knid of glue is going to stick to this type of plastic. Where I work we had plastic fabricators that could "weld" plastic like this. The welder used compressed air and had a heating element and various tips like a torch. If needed, filler rod was also used just like brazing. Basically, it was "remolding" the piece. Problem is, I don't know where to tell you to find someone that does this.

If the bedliner is polyethylene, and many are, heat welding is the only possible repair.

I suggest you stop-drill the cracks for now, which should prevent them from growing. You need to know what sort of material the liner is made from. I suspect it's ABS, which can't be fixed with adhesives; it needs to be welded.

I've used J B weld on things like that before, it will look like a patch though ! Good Luck Mike

Do a search online for HDPE welding rods. They come in several colors. You can purchase a welding tool from them but it is basically like a soldering iron. The welding process is somewhat like brazing you just heat the parent material, keep adding filler rod, and be sure to tie the 2 pieces together with a weaving action. Believe it or not it will look like a bead of weld when you are done. I use this on PE crates all the time.

Most likely High Density Polyethylene and can be repaired by the plastic welding process or heat sealing a patch on the back side. We call it no break or bucket grade. They also make a no break polypropylene. If it were a polypropylene no break material it would take a different material in the plastic rod. Not many glues work well on either material. Both are materials used to contain glues for shipping. ABS was mentioned but it would not be ABS as gas spilled on ABS would dissolve it. We used to glue two ABS parts together with MEK. I fuse two polypropylene parts together every day with heat. The same with polyethylene in the past.

ABS can be solvent welded, plumbers do it every day. But petroleum oils cause ABS to crack, so it would be a bad choice for a bed liner.
