sanding between coats
I am building 3-5 coats of Spar varnish and used gloss, so far.
Below is the result of sanding with 2000 grit sand paper, it abraded the high spots and they turn into white specks from the scratches. So far the next coat seem to cover these specks and the next coat of gloss looks nice again.
however I am about to change to satin as it is the final sheen I want and I am wondering if it will cover the sanding marks as nicely as gloss.
Do you think Spar Varnish does not like to be abraded in that case, how to rub out the final coat without causing these white scratch marks? Because I don't recall this problem as much with polyurethane.
Or do I need to let it dry more before sanding?
