Re: Thinning Silicone - Acetone?
My advice is just take your time, and resign yourself to a "it takes as long as it takes" attitude. Don't worry about doing large areas, but manageable sized portions.
Thinning the silicone might cause you other problems that you didn't anticipate, such as adhesion/coverage problems.
Be patient...there's no room for a rushed approach when doing this sort of thing.
