Epiphanes recommends their brand paint/varnish thinner, "...or a good quality mineral spirit..." for their high gloss clear varnish
If I happen to be buying
Pettit/Z-Spar T-10 thinner to use with Pettit one part polyurethane
(#3175), is it okay to use it with the Epiphanes varnish
, too? IOW, is it just a good quality mineral spirit?
Should I save the $$ and just use regular mineral spirits to thin & clean up both the paint
and varnish? $19 for a quart of thinner does seem outrageous.
