Can Arm R Seal be thinned with anything other than the recommended General Finishes thinner? I am working with a walnut slab table top and assume I want to thin the Arm R Seal by at least 50% to start. Don't want to darken the color but do want to deepen the grain.
I have the Arm R Seal but no thinner. I don't have a dealer nearby, have to order via internet and would like to do some finishing this weekend.
thanks!
