Can I use Gorilla Glue on my car bumper?

While a popular house product, people may ask, “Can Gorilla Glue be used on cars? any of their products are great automotive glues.

Preparation

The first step is to try and to bring the edges together to make the cracks as close as possible. Use a dremel tool to V groove out the cracks about ¼” wide. Fill in the grooved cracks and let the resin flow in to fill the crack level with the surface. If you notice very small air holes in the resin do not worry about them.

Fill The Hole

Using the ABS sheets that come in the kit I used a pair of tin snips to cut a piece to fill the hole. I then put the resin around the hole and put the cut piece into place. Using a plastic body spreader I smoothed out the filled area.

Cure The Resin

Let the resin cure for 24 hours. Sand the filled area. Continue to sand until the area is smooth and even around the edges. It is ok to layer the fill as the resin will chemically weld to the previous layer just as it does to the original plastic of the fender.

Final Prep

When all of the low spots are filled and sanded smooth we are ready to move into priming and spot putty application. I use a primer that has made for plastics on the label. Apply the primer in short even strokes. When the primer is wet you will be able to see any imperfections. There will be tiny air holes in the filler and this is normal.

Finish Paint

When you are satisfied that you are ready for the finish coat wipe the area down with a tack cloth. Spray in even coats do not try and put too much paint on at a time or you will cause runs in the paint. Many light coats are better than fewer heavy coats. Make sure you put on enough in one coat that the surface is shinny.

How to fix a crack in a plastic welder?

Step 2 – Splits and Dents

  • Splits should be pulled together as closely as possible using high adhesive masking tape from behind the fender. You may have to use multiple strips of tape before good adhesion is acquired. Take the plastic weld solution and distribute a copious amount across over the area where the split has been sealed. Aerosol hardeners which can be sprayed directly on top of the plastic wel…
