I do not agree completely with Bob.....but between Skip , Rob, and Bob, Speed does have some great moments.....but I don't need them 200 times.

I shoot duplacolor , always over primer and if fresh DOT3 does not work then 91%alcohol will work.
A plastic snap lid container will work wonders.
After 12 hours scuff it with a green pad and recover the container.
MAKE SURE IT IS UNDER THE LIQUID!!!!!
I find 12 to 36 hours are needed.
