Product Description
Use Filler Prep BEFORE applying filler
Chlorinated Polyolefin
Whenever you apply filler to TPO or polypropylene plastic, ALWAYS apply Filler Prep first. The chlorinated polyolefin resin that is in Filler Prep serves as an effective adhesion-promoting resin for coatings and fillers applied to polypropylene (PP) and thermoplastic olefin (TPO).
Better Adhesion
The addition of an adhesion promoter improves bonding by penetrating into surface irregularities (such as pores, holes, and crevices) and mechanically locking onto the substrate.
- Made in USA
- Precision: The brush-in-cap allows targeted application, ensuring coverage only where needed.
- Stronger Bond: Using Filler Prep helps get a better featheredge when sanding. No peeling.

Product does some heavy duty cleaning but it is harmful so factor in the extra cost of proper health gear needed $$$.

Prior to I did not use a promoter as a result my dash cracked at the repair. Let’s see if it stays together now 🙂

I come almost empty, all product was out in the wrap bag ,only less than a quarter was left on the bottle

This is supposed to make a good bonding surface, but it requires you to sand the project first anyways so this is useless. Just sand your surface before putting the dash filler on.
