Exclamation Emerald urethane Sherwin Williams

Hello everyone! I have an issue with this product I've never used before, Emerald urethane. Long story short, I'm fixing a couple of doors that have some brush marks on em and the finish needs to be spray finish, with the Emerald urethane. So I try what I know usually works for me in obtaining a smooth finish, I wet sand the areas. Although when I do this, i am getting white build up from the urethane paint that almost becomes pasty. Am I not to wet sand it or even just sand it if it's not cured completely? I wiped off the residue before I sprayed the doors. I gave 2 light coats but only let 1st coat dry for maybe 20 mins. Brush Mark's were still slightly visible but looks like I created a diff problem as the spray left an almost fog look. Keep in mind that I didnt paint the doors originally, I'm just fixing these doors that another painter did.
Any suggestions on what to do would be greatly appreciated. What size tip do I use and how do I go about sanding these areas?. I'm using a 320 grit. Thank you

Read the back of the can for application instructions? 20min dry time for a modified urethane is not enough. You better have a perfect surface, these new modified alkyds contour to the surface like glass and show every imperfection, BM advance is the worst in this regard
