I recently switched to this putty pictured, I like it and yes the clean-up is quick. What I learned let it sit for days, and water cleanes it right up.
The question and I know the answer. Before painting, the best practice is to wash ..... soap & water (buzzer sounds!)
Thinking 1 thinner wash
2 Or some flat covering the putty & shoot the primer. I sand after primer so the coat of flat will have no bad effect on the finish.
Just some working shots
Timed this because I was impressed after I used it . Reading an earlier post asking the same question you have.
