How To Repair Deep Scratches In Plastic Bumper

Hither we have a lower bumper fascia on a friend's 1999 Ford F-150 pickup that was damaged by his teenage son driving the truck into a ditch. The part is merely $106, so information technology wouldn't brand sense for a shop to repair this in a typical state of affairs where the repair costs are covered past insurance, but it demonstrates the steps you lot'd use for repairing whatever textured plastic.

Pace one

Clean the plastic with lather and water then 1000 Super Prep plastic cleaner. Heat the distorted area with a heat gun and press the plastic back into position. Quench the plastic with a wet rag once yous've got it reshaped.

Step 2

Employ a hot air welder and the R13 polypropylene strip to repair the crack on the backside. If you don't take a hot air welder, you can also repair with R10-04-03-BK FiberFlex rod and 2045W Reinforcing Wire Mesh.

Step 3

Once the weld on the backside cools, squealer out the plastic on the frontside using the 6122 carbide burr. Make the groove nigh i/2" wide and at least halfway through the plastic. Scratch upwards the groove with a 50 grit Roloc and feather back with 80 dust in a DA.

Stride 4

Melt R10-04-03-BK FiberFlex welding rod into the v-groove on the front side. Don't melt it with the base of operations textile; FiberFlex is not a true fusion rod but rather a thermoplastic agglutinative that sticks very well to TPO and PP.

Step 5

Once the FiberFlex cools, sand it shine with 80 grit in a DA. 80 grit tends to make the soft TPO become fuzzy, then sand everything with 180 dust to remove the 80 dust scratches.

Stride 6

Utilize 1060FP Filler Prep adhesion promoter and 2022 SMC Hardset Filler to fill up in any depression spots and imperfections. Profile with a block, then DA with 180, 240, and 320 grit to remove all the fuzz from the TPO.

Step 7

Accident dust costless, utilise 1050 Plastic Magic adhesion promoter, then spray on 3804 Flextex VT to simulate the original stippled texture pattern. In one case dry out, lightly rub with medium scuff pad to remove dry spray and cobwebs.

Stride viii

In one case you have the texture the way you want information technology, apply the matching Bumper & Cladding Coat color. B&C Coat matches 41 different shades of gray, making it like shooting fish in a barrel to find a shut match for your situation.
