base coat clear coat help

i have a 67 mustang that i started spraying with DuPont base and clear yesterday. after i got the roof sprayed with base coat my gun stopped working and i had to stop. it has sat for 24 hours. i wiped it with Eastwood paint prep and it discolored the base a little bit. can i spray over this or should i sand it off? i have epoxy primer under it.
i would appreciate any help, thanks.

You should NEVER wipe base down with ANYTHING. You are going to have to sand/scuff it anyway because you let it set. let it sit for and hour to let the solvent get out completely (if you havent already) and then sand. I don't think you will have to remove completely.

DuPont paint says to remove if not cleared within 24 hrs.
That seems excessive and I know a lot of people let it sit
longer than that without haveing any issues.
So it's a judgement call, I'd probably scuff it real good and shoot
more base and clear it-but it's your call.

Where did you hear that? I have shot DuPont for 21+ and have never heard that. As a matter of fact, I have had several DuPont reps say if it ISN'T activated then it really doesn't matter, but if it is activated then you have 12 hours. Then all you have to do is scuff and apply another coat or two and then clear. I don't paint until I'm ready to do the whole job. If you can't clear it within a hour of basecoating, you weren't ready to paint. I don't understand WHY you would base coat something then WAIT 12-24 hours to clear. Basecoat is designed to be cleared as soon as it has flashed off.

Thats what I say too.Dont even wipe your hands over it...
You should resand it because there will be wipe marks there that you wont sse until you clear...
If it wasnt for the wiping down part ,all you need to do is scuff and keep on going but it still takes at least two to three coats to fil the scuff scratches...

It only takes a couple of hours. I shoot the middle color (if its the factory type where the top color is on the top and bottom and the other color is in the middle.) first, let it set for 45 minutes and lay my fineline. Mask the center, tack the vehicle (you will be able to tell if there is over bad spray that needs to be scuffed off and if there is re-tack when done). Spray the other color, unmask the middle 2-tone and clear everything. Done it HUNDREDS of times. I have NEVER had base coat exposed for even 12 hours.
