Isopon P40 in the 600ml tin is the small size of this glass fibre reinforced polyester paste, sized for one or two holes rather than a big project. Use it to bridge a hole or gap that plain filler would sag into, on any metal including galvanised steel or on GRP, then shape it once hard; the hardening solution comes with it.

Good to know

• What do I do about the rust round the hole? Filler and resin do not stop rust, so grind rust back to clean, bright metal before you repair, or it keeps spreading underneath.
• Is it a structural repair? Rust in load-bearing parts of the body, such as near suspension or seat belt mounts, needs a proper repair, normally welding; filler or glass fibre there fails the MOT.
• How do I shape it? Polyester filler can be shaped with a body file while it is firm but not fully hard, which saves a lot of sanding.
• How much hardener do I add? Stick to the hardener amount on the pack: too much can stain the paint over the repair, too little leaves the filler soft.

Which one?

For more than a couple of holes, P40 also comes in 1 litre (P40/2) and 1.85 litre (P40/4) tins. For the finishing coat on top, Isopon P38 Body Filler (P38/2) sands to a smooth finish.
