Hey could i use alcohol or nail polish remover as a paint thinner?

No. Either could affect the paint in a negative way. If the paint is water based latex, then adding a small amount of water at a time and stirring like mad will thin the paint. If it's an oil based paint, the only good solution is paint thinner. This will thin the paint without damaging the chemical make up of the paint and ruining it's final finish.Hey could i use alcohol or nail polish remover as a paint thinner?
Usually, no. Depends on the paint. Every paint can has clean-up directions.
