These Projects refer to Boating, but you can use the same methods for Any of your own Projects.
Polyester resin bonds firmly to a wide range of materials including wood, metal and concrete, and makes strong, durable repair patches which are waterproof, rotproof, non-rusting and resistant to weathering.It can be used to repair almost anything, and is especially ideal for mending boats.
Minor scratches on GRP surfaces are quite easy to repair simply by filling with gelcoat resin, or with Gelcoat Filler. It may be necessary to gouge out the scratch (preferably with a V-shaped tool) to ensure the resin locks sufficiently. Leave to cure, then smooth down with Rubbing Compound.
Small holes, cracks and dents in most GRP, metal or wooden surfaces (other than boats) can be filled with a mixture of lay-up resin and filler powder. You can buy ready-made stopper pastes or bodyfillers,of course, but the advantage of mixing your own is that you can make it to the required consistency (and, in larger quantities, it is more economical).
