My first 'real' project has been shop cabs. I decided to spray finish them. So I went with with shellac because I read it's forgiving. I ran into most of the problems that a novice would when spraying, but overall it went well. My question is 'how do I repair the mistakes'. I made several mistakes but the most obvious mistakes are a few runs. I tried rubbing them out with alcohol, but it seems to thin the thin parts and leave the thick, darker run intact. Should I sand? Steel wool? Am I doing the alcohol rubbing wrong?
