http://www.autobody101.com/forumsSome of the paint is hazardous to your health! PPG was what I used till I got a couple of gallons of DP series primers lacking pigment. Had to take it in to them Den's in Belleville back then, same place Jim recommened, second time they believed me and it didn't cost a trip.
Different brands do spray differently, way back in HS we were taught Dupont, then I did a door in Ditzler.... good old Mr.McConnell (shop teacher) let me learn the hard way. I did a door patch on a 65-7 corvair in metallic blue. Well.... Mr C did hand me a pair of big scissors to cut the runs off when the got to the door edge......he got a good laugh. Well I have to say I've pulled that trick twice now....once a couple of years ago on my boy and many years ago on my old buddy painting his truck.
Do the insides 1st, make your mistakes where nobody can see them. Keeping the moisture from ruining your paint, it will cost a few bucks if you want to spray anytime or you can wait till conditions are better. You can do it just takes some time and money.
