This page is dedicated to a tutorial that came up by accident. You see, I had no intention of ever using the hardset plastic filler for the purpose of repairing plastic, however, it was the first opportunity I had to utilize it. So me being the person I am, decided to use this opportunity to make a tutorial on how I used it for that purpose.
I was removing a plastic panel from the rear cab of my truck in order to add expanding foam to the insides of some hollow panels to help keep vibrations to a minimum, when it happened. I pulled too hard and the clips held their place....thus snapping a piece of my panel off. A minor setback as I remembered I had the supplies on hand to do a repair.
Materials Used:
Damaged plastic panel
CA glue (super glue works fine)
Drill
Smallest drill bit you can find
100 grit sandpaper
220 grit sandpaper
SMC Hardset Filler from Urethane Supply Co)
Spot Putty (from Urethane Supply Co)
Okay starting off, I glued the broken piece back on the panel using CA glue. Once that was done, I scuffed the area around the damage with some 100 grit sandpaper in order to ensure a proper bond to the plastic panel. I also used the smallest drill bit I could find to drill holes on both sides of the crack, again, to aide in making the strongest bond possible.
Next step, using some SMC Hardset Filler (Urethane Supply Company PN 2020-T) I mixed Part A and Part B together in equal parts, then spread it on over the cracked area and around the scuffed area. You want to make sure you spread it to a large enough area around the damage area to ensure reiforcement and help in strengthening it.
I had a chance to quickly sand down the plastic filler and then applied some spot putty to the small imperfections. I then sanded that down with some 220 grit sandpaper.
Coming Up:
*using SEM Texture Coat, apply texture to repair piece
*using SEM Classic Coat, paint the entire panel to color match rest of interior
