- A two-component bridging filler paste designed to repair damaged body panels on vehicles.
- Can be used on bare steel, and original paint surfaces.
- Polyester glass fibre filler is a two component chemical paste used for the bridging of holes and rust in surfaces such as steel and GRP, form a very hard durable surface and can be sanded and shaped if required. It is easily covered with standard polyester filler or can be over-painted directly.
Surface preparation and instructions for use:
Polyester filler can be used on the following surfaces:-
Bare steel, degrease and abrade with P80 paper.
Original paint surfaces (with the exception of thermoplastic acrylics) degrease and abrade with P80 grit paper.
GRP degrease and abrade with P80 grit paper.
100 parts by weight polyester filler,
3-4 parts by weight BPO hardener for polyester filler.
The exact mixing ratio is not critical, although over or under catalyzation may affect the gel time.
Do not greatly over catalyse the paste as this will not significantly speed up the gel time and could lead to bleed through and bleaching problems when over-painting later. Staining may also occur where too little hardener is used.
