Like the title says... I'm a newbie regarding automotive paints.
Lately I sprayed Mr. Surfacer -> TS14 -> 2 part autopaint and all went well.
After the clear I sanded it down then noticed that the silver I used was irregular...
Reading about a simular situation, I sanded off the clear and misted another coat of the silver. Due to the fact that the 2 part clear I used was sXXX, I used Mr. Super Clear instead. Now here's where the major f-up occured. I obviously should have waited longer until the autopaint had cured, since the Mr. Super Clear ate right down to the TS14.. see pic:

This was 3 mist coats 2 medium and 1 heavy.
My questions:
How long should I wait before using normal hobby lacquer over an automotive paint? (This was done with about 10 minute intervals)
Is there anyway to strip automotive paint without harming putty work (Tamiya fast type)?
Thanks beforehand for any replies.
