PLASTIC PARTS
4.
Grind polypropylene surface carefully. It melts easily due to the heat generated by friction. If melted, remove that area.
Also, grind the area where solvent is to be applied.
5.
Apply polypropylene primer evenly with a brush over an area wider than the area to be repaired.
Dry it at 20 C (68 F) for more than 10 minutes.
6.
Mix main filler material and hardener at a ratio depending on paint specifications. Mix filler material and apply over the
damaged area.
NOTE
•
Mix main filler material and hardener so that no bubbles are made.
•
Work immediately after mixing filler material because the filler material hardens quickly(in about 5 minutes).
•
Dry it at 20 C (68 F) for about 30 minutes before sanding.
•
Filler material consists of two types of epoxy.
When the filler material hardens, you will have a desirable finish with flexibility like polypropylene.
•
Use only filler material designed for use on polypropylene bumpers.
Do not grind continuously.
