If you prep the existing single stage paint using a block and 400 grit or 600 grit paper is fine...33Willys77 is correct with respect to taking a long time and keeping the car straight...if you don't use a block. If you know how to sand a car by way of properly using a block, the body work will stay straight. Also, if you sand through the SS color, (depending on what's underneath the Single Stage) and you don't spot prime, you could have lamination problems or ringing around the area you broke through...again...depending on what's underneath your single stage.
Hope this helps.
Color is a solid color no flake. Whats underneith was epoxy primer as bottom layer followed by 2 coats of 2k Urethane high build primer. Filler work done then 3 more coats of 2k Urethane high build primer. Car was then blocked with 400 grit and shot with Single Stage Urethane. I will sand the car down to get runs out then block with 400 or 600 then go to a BC/CC system. After reading and some videos I have decided that it may be for forgiving for a beginner such as myself.
