Apply the gelcoat using a brush if you're covering a small area. To apply the gelcoat with a brush, dip the brush in the gelcoat so there's a liberal amount of gelcoat on it. Brush the gelcoat onto the fiberglass using short vertical strokes. Avoid spreading the gelcoat too thin or you'll get stroke marks.
Moreover, can you Fibreglass over gelcoat?
Its sanded and more gel coat is applied. Also when doing a repair or re-gel coating it's not real a chemical bond because the gel coat or glass/resin that your applying on is already cured, so it will be a mechanical bond(after you sand), but it will stick the same to gel coat or fiberglass/polyester resin
One may also ask, how do you gelcoat a fiberglass boat?
Four Steps to Gelcoat Restoration
- Step one: Remove all surface dirt. To remove the surface dirt, wash your hull and topsides with marine boat soap diluted in water.
- Step two: Remove the stains.
- Step three: Remove the oxidation and restore the shine.
- Step four: Protect the shine with a wax.
Absolutely.. there's never been a need to 'remove' gelcoat but it needs to be dewaxed and thoroughly cleaned - a scuff sanding will help but no need to grind it all off. The crappy job is repainting over old paint - especially if you don't know what was used the first time.
