What thinner?

[Thailand]

A few scratches etc that need tlc.

 

Have the right paint, will probably brush/roller. What thinner should I use and what proportion?

Just basic cosmetics for an old banger.

You need to tell us what specific type of paint you have before anyone can answer about thinners.

My óld banger' simply uses foundation and some powder, works a treat. No scratches or wrinkles to be seen.   PML
