Lifting paint

    Had a problem with paint lifting in a door jamb yesterday. The car had a new door and quarter installed and I jammd both of them the day before. The door was reinstalled and I painted the door and quarter yesterday. Where the door and quarter meet the paint wanted to roll back , my guess this is where the base was eating into the fresh clear from the day prior. I sanded the affected areas today spotted the jamb and life is good again. My question is what can I do to avoid this in the future? I work in a production shop and letting the clear cure longer really is not a option, I think that my reducer temp could have played a factor in this as well, I used med reducer to give the metallic time to lay down and the base layed wet a little longer than normal. I use sikkens base and lesonal clear.

    how often does a problem like this happen? i think if you use foam tape to close the gap you should be fine. try using the carsystem brand instead of 3M, almost 40% less.

    I used the foam tape in the jamb and it lifted on the very outside edge of the tape, the door was sitting in a little more than normal due to not having the seals or hardware in it. I have not had this problem before but would definately like to avoid this in the future. The additional three hours it took to get this thing to behave really threw the day off.

    I can accelerate it. Will probably just do that from now on in my jambs. At least until it warms up a bit. Thanks for the tips. I have been lurking on this site for quite some time and it has helped me get back to speed. I have been away from painting for quite awhile, and I have found a lot of good info on this site.

    more than likely when you jambed you sprayed part of the outer panels as well then sanded that back to have a nice surface to paint on. Sounds like the solvents are getting under the clear hitting the base (kinda like what happens on a sand through) you can add some hardener to the base when you jamb (or all the time is better) this will help when recoating sand throughs

    I ran into the same problem awhile back. I switched to a faster cut-in clear and seems to have cured the problem since.

    i’m going to have to go with Ding on this one, throw a few drops of hardner in your basecoat and this problem will not continue, i ran into this issue with ppg a long time ago, the reducers are very agressive and fire up the basecoat, but if you put hardner in the base it locks it right up
