thank you for reply

I have done quite a few parts in "satin finish" by wet sanding to 1000 and then used ordinary wax release... no problems with demoulding...

Normally I just wet sand the part after release for m a polished mould, then polish with coarse compound, and use wax on top..

Seems to be just as durable as any satin clear coat, especially when using GC50 gelcoat ..

"Sapere Aude"... Dare to KNOW!

The written word is the only truly efficient vehicle for transmitting a complex concept from mind to mind...

103% of all people do not understand statistics...

Do not adjust our mind, theres a fault in reality :-)

thank you

but is it durable, or first mud will leave marks?

Hi

i haven't been doing yet a mate/satin finish.

is there a special release agent for mate/satin finish or just wet-send without polishing?
if only sending which grit 1500 or less ?

thank you for answers
