Use epoxy and some q cell and make a putty fill the graze with just enough mix then apply an over head projector sheet or similar plastic ( avaialble on alot of packaging these days) and tape down. should barely need to sand if you do it correctly.

Q-Cell is a powder you mix with the epoxy to make it a stronger glue and also make it easier to sand.

Much easier to use International Epifill as it is just a 2-part mix with the powder already in.

Binks Marine in SA will have what you're after.

Just make sure the gash is clean and dry before you use the epifill, maybe rough up the inside of the gash with some sandpaper to help adhesion. Mix it up, fill the gash and smooth off with a paint scraper or plastic spatula. Epoxy doesn't shrink as it cures so you shouldn't need any sanding after it's cured.

Oh and leave it overnight to cure.

Hope that helps.

thanks mate

excuse the ignorance, but

what is q cell and where can I buy, can you use straight epoxy?

also

Does the putty not stick to the overhead film, why is this film needed, does it prevent expansion?

Adelaide Molding and casting on Marion Rd have all the small amounts of epoxy, fillers, colourings etc.

Good people to deal with plus easy to order online

thanks for all the replies - love this forum for usfull info.

the sellies product and international epifill both sound like good products, I think I will go down to Adelaide mouldings as they will probably have a good idea of material interaction and be able to supply the correct one.

It seems like most epoxy materials do not react, has anyone every seen a reaction that has destroyed the board??
