Thank you Don. Checcked few videos and he seems to know what he is doing....alhough I tend to wear more PPE. Got few pointers there.

Thank you Steve. I was making an order of black gelcoat, polyester resin and some perforated membrane. I added a small can of talc on the list and some microballoons. Now I only have to figure out correct laquere to mix that talcum powder...used to use some urethane varnish for boat and that sort of stuff. That brand is not anymore available, it would probably have survived most of the chemicals.

Water based products seem to be big time en vogue now....those create potenttial trouble with PVA release film, unless completely dried.

Would a thin epoxy do the trick? I would not need much, all parts are pretty small.

Years back when I used to use polyester resin for moulding, the worst clean up was when it got on your nails - seemed to have a great affinity for human nails  :bugeye:

So gloves as PPE I reckon are a GOOD THING in this case - seem to remember they were flimsy polythene things that fell apart.

Pekka, laquer is a specific type of fast drying evaporative finish. It's not oil based varnish or enamel, or a polyurethane.  It produces a very thin coating, high gloss, super fast drying.

This is what I use:

I don't think talc would work as well in other finishes. The would seem to be too thick, and would dry slowly, as well as be difficult to sand, by comparison. Epoxy would be even harder to work with, and goes on in gloppy drips. Lacquer is very fine, and the talc is the main thing you are sanding away.

And don't use microballoons except in a filler putty, if you want a fine finish.

Thank you, I'll need to follw that lead.

I put some pictures to enertain. I am big fan of router, even drill holes with it.
