finishing varnish sanding back polish, newbie question
A have a question regarding the finishing, sanding back and polishing of an oil based varnish (feast watson clear varnish).
I've applying about 4 coats on a small table top and im wishing to sanding back the final coat with 400, 600, 800, 1200, 1500 and buff with auto wax.. my concern is im probably going to sand through the top coat to get everything smooth and even.. when this happens, is it likely that the previous layers of varnish will be noticeably visible?
maybe I got impatient.. I waited a day from the last coat and sanded with 400g using a random orbital sander. It has smoothed things out alot, however, i noticed I may have gone through the last layer and little layered bits started to appear.. i stopped and thought maybe it hasn't cured enough.. so, my question is, should i wait for it to cure, perhaps a week? or is it likely i will have to reapply a thicker final coat?
