Paper in Intercoat

Barry, here are the pictures of my intercoat mistake we talked about on the phone on Sunday. I did as you suggested and everything worked out fine. I got done with my clear about eight o'clock tonight and none of the spots showed so I am very pleased. Thanks again.

I will explain for everyone else. Saturday morning I sprayed three coats of Diamont base with 30-45 min flash in between. Then I sprayed two coats of intercoat clear. Sunday mid-morning I taped up for my stripes, sprayed 'em and waited about an hour before I untaped. The result is in the pictures. Apparently solvents were still coming out of the intercoat when I retaped. I didn't feel sticky and I never left any fingerprints so I thought I was safe. As Barry suggested I rolled it out in the sun for about an hour, rolled it back in and sanded with 1500. All came out well. The only thing we could figure was the high humidity yesterday slowed the drying. Anyways, it's all good now. Just thought I would share.
 
Thanks for the pictures, it is diffidently solvents coming out still but why after setting overnight makes no sense whatsoever with the two products you used.
Unless the 895 was just too slow for your temps???
 
All your flash times seem long enough by far, I wonder if the coating you put on after that masking was able to penetrate the paper. Did you use coated paper, or plain stuff?
 
Thought the same thing about the stripe coat penetrating the paper.
In any case the intercoat protected the base under. Better to sand problems out of the intercoat than risk wrecking the base color.
 
I think the temp in my garage Saturday was about 80-85. I know Sunday it was 90 by 10 a.m. Also had about 85% humidity on Saturday as well.

I wondered the same thing Crash. I used the regular "green" paper from a local paint supply store here. I DID over-reduce the pearl for my stripes, BUT I made sure to do light even coats with plenty of flash in between and I never even thought the paper got the slightest bit wet. Who knows? LIke I told Barry if there is one person in a thousand that will have a problem, you can bet that I will be that one!
 
You're money ahead to buy the coated paper. imo. If you look at photos of pro jobs, it's rare to see any plain green paper. The only green paper we keep is a roll of 36" that gets used for various things, always well away from wet paint.

It doesn't take much to penetrate uncoated paper.
 
Everything the guys point out is true but I still think looking at the tape mark it was the solvents in the undercoats just did not get out, like they should, could have just been that coastal humidity, I just don't know.
Everything we talked about on the phone you did perfect, so its either paper, tape or solvents and sometimes just no for sure answer.
 
Whatever it was is taken care of (I hope.) After sitting in the sun for a while it seems to sand ok. I got four coats of clear on, set in sun for a day, blocked with 400, set in sun for another day, and three more coats of clear. I haven't seen any solvent pops and the clear sanded really well and seems to be stuck. So far it's looking fantastic!
