Here it is boys, something I like to think as the last step in getting a perfect part!

After stepping into the clearcoating/painting business I can tell you, with or without a paint both it is a total PITA. I cant stand clear coating a part after de moulding, then the clearcoat gets wavy or a bug in it. then i san and polish, still not perfect.

I'm starting to learn this real fast; the key to a perfect part, is taking a mould from a perfect part and polishing it there. I plan to make some really perfect molds, then try this.

The site says you can brush it on, we for my size parts that would be really connivent. Now matter what the surface of the part will be perfect but if your paint strokes on the back are to thick you may see your weave get a little wobbly.

When making parts smaller than ".5 meter" I think my cup gun is a bit much? think an air brush system would work?

Thanks guys, Sounds like I will be spraying it on. My question about the pva was not if it would de-mould well but if I spray it on the pva, will it lay right?

 

Guess I need to just wait tell it gets here and give it a shot. I want to have it on thiere thick enough I could do some minor sanding if needed.

 

im at the point were I am cuting back the amount of waxing I do,just 2 times then pva.

 

I can say coming from a noob I was using was to much, so much that the wax was efecting my part surface. NOW I know that just a haze of wax is al you need, otherwise more work later....

The gelcoat will go down onto PVA fine. PVA is a much less repellent surface the wax or chemical release agent so, although PVA comes with plenty of its own problems, it does make it easier to put gelcoat down onto it.
