Re: [ATM] Varathane



Aye, I second Curt's recomandation here...start with a solvent, and in this 
case the least harsh first, and move to progressively harsher stuff if that 
doesn't work (so simple mineral spirits next..before resorting to laquer 
thinner...and finally acetone, or MEK which will surely romove the offending 
coat, but as mentioned may effect the stain)...It might not hurt to give the 
project some time to dry and air out between solvent experiments to give the 
thing a bit of time to relax from all the multiple chemical inputs....
