sometimes the tech writers for products actually get ahead of the tech. department. As for thinning it out anymore with laquer thinner: I've yet to see a laqcuer based product get thinned out that little. Usually it's a 100%-150% thinning. Now the back of the can is telling you "reducer?" That's a different ballgame. Chances are it's not laquer based if they're referring to "reducer." Your best bet: call Eastwood and ask your questions of the tech department.
