I'm working with a 2K urethane primer and have always been under the impression that if you didnt topcoat within the alotted window, you could simply scuff/sand the primer and apply the next coat without any problems. I've never worried about applying the next coat of primer within a certain amount of time if I scuffed/ sanded the primmer before the next coat.

I'm now at the point of wetsanding, and thought that I'd go ahead and wet sand even if it were a few weeks before I could get to the BC/CC. From another post I read, it appears that I may need to topcoat within a certain amount of time even after wetsanding.

Do that sound right? If it's true, I better hold off on wetsanding until I'm ready to apply the BC/CC. ( I was hoping to wetsand and then apply the BC/CC in a few weeks). Thanks for any clarification.

No problem as far as I have been told smile.gif Just remember to wipe it with a final wipe before you shoot your bc. smile.gif Make sure it dosn't get any overspray on it while it is sitting around though.

IMHO the "work" is done have fun and just shoot the bc/cc that's the easy fun part!

Personally, I would scuff it again if it sits for more than a few days...just a grey scotch brite would be ok.
