Ok I just painted the top of my 65 c10 white thursday. I had a couple spots that ran in the sealer. SO I painted over the runs then today I sanded the runs out cleaned and repainted the bad spots. The paint did not take it wrinkled up. My question is Sould I resand then reseal the bad spots then repaint or do I have to primer then seal then paint. I am using single stage urathane paint
