Prepare the area smooth and ready with fillers as you have done, then spray with a waxed gelcoat. Once that is cured you wet sand to 1500 and polish. You should not use paint clear coat materials for the mould repair. Fastacraft Facebook page

After this process, when I have the surface as desired, I made the attempt of using car clearcoat, with really good results. But it don't last smooth many mould uses, it tends to wrinkle and lose strenght. Parts are made with polyester resin, hand lay up, and room temperature curing. Any experiences on mould repair or last coat to apply to get a shiny result? Thanks. Pedro.
