Sometimes you are going to get screwups. it is called learning.
Here is something I do when trying something new or unfamiliar. Keep careful notes, detailing everything you can think of that may affect the paint. Temperature, time of day, humidity, application techniques, surface prep techniques, everything that may affect the paint. Write down the results. You will eventually end up with log book of what works, and what does not.
Do not forget to follow the directions in the paint product lead sheet as much as possible. The local store you buy the paint at may also have some good advise for you.

|89blue7.3||thanks brian! i definately jumped into this type of paintjob with both feet. i didnt expect it to go perfectly. but it did at first so i was all excited. now its giving me fits. when i do the bed and hood next it should go better since ill actually have time to do it from start to finish in one day without having to come back and scuff a cured surface, itll be applied within its recoat window. atleast thats the theory im holding on to! i really do appreciate your help.|

Now with a few things piled on it gets harder and harder to give any advice on your specific job. Generally speaking the substrate that is wrinkling is too thin, or not properly catalyzed or something like that. The solvent from what you spray on it is kicking it's butt. Why is it doing this, because it isn't a "barrier", it isn't blocking the solvents from getting thru it. At this point only you can tell what you can do to change this.
The truck is looking AWESOME if that counts for anything.

|89blue7.3||hmmmmm... kinda thought somebody wouldve commented on my project thus far. well... its still happening and im really getting frustrated. i read some more posts this morning about wrinkling and the like and one of the problems suggested was improper sanding. so i resanded the area im fixing with 320 wet/dry instead of just scuffing with scotchbrite. i wiped it with wax/grease remover and immediately followed with a clean cloth (as recommended in another post). i went and helped dad with a project for maybe an hour, came back and sprayed my silver and wrinkled it with the plastic sheet. and dammit if the backside of the cab didnt start pulling up on me again!! i let it dry for half hour or so and sprayed my candy apple red over it. the areas it pulled started to pull alittle more. at this point im just going to clear the friggin thing after dinner and be done. i cant afford any more time lost messing with this truck as i need it finished and driving to pull my camper at the end of june. any more suggestions?? could too much reducer in my silver cause this??|

It won't automatically resize on photo bucket, at least I have never experienced that. You CAN resize on photo bucket but when you upload to it, the photo will stay the same size. You can make the photo any size you want and post it here.

|89blue7.3||thank you for the response brian. i had this problem a couple times before when dealing with just the base. so my thinking was maybe the light coat of clear might serve as an intercoat of sorts, that theory evidentally did not prove true. maybe inadequate sanding is more to blame?? ive just never dealt with multi-colored paintjobs before. never had any trouble with adhesion in single color. but those i could do complete in a day. this i was not ablw to. i tried attaching pics but the files were too big.|

When I see "a light coat of clear" that is all I need to see. Wrinkling is caused by solvents getting thru, or under an edge of a previous substrate. It could be years old as in a 1k enamel sprayed over a poorly sanded original paint. You sand a chip out and now the next paint or primer you spray the solvent in it gets under the edge of that old 1K enamel and lifts it up wrinkling it. It happens in that case because the enamel isn't sticking to the original paint good because of the poor sanding, and it's a 1k and the solvent soaks into it easy on the edge.
The exact same thing happens when you spray a "light coat" of clear, it isn't a barrier, the solvent from the next product soaks thru it and lifts it up wrinkling it.
There are other things that could be at play here such as recoat windows, there is a time with some products that you can respray it, be it two hours, or after 24 when it is more fully flashed and or cured.
It's kind of a partially cured paint or clear is like a too thin sheet of protection. The solvent from the next product soaks thru that thin top layer that has dried and gets under it, much like the old 1K enamel example.
But I am thinking if I read your post properly it sounds like the thin coat of clear is the problem.

new guy - help with paint screw ups!!
hello. first off i am by no means a professional. i have painted 6 vehicles over the last 15 years for myself or family. all single color jobs. on my most recent project (1992 ford crewcab dually with a cummins swap) i wanted to get alittle creative. so i designed a 3 color paint scheme. im using Kustom Shop paint from tcpglobal.com. what i am doing is base coating entire truck black. then a solid silver stripe down the middle. on the top side of the truck i layed down a really wet coat of silver and wrinkled it with a plastic sheet. then candy apple red over that, followed by clearing the whole thing. i am having alot of trouble with subsequent coats lifting the previous coat and making a wrinled mess. i dont know if the dry time is my problem or what. when i first did it on the outer surfaces of the truck it went fantastic (thank God). and that was a long setup time to tape off all my graphics. scuffed the whole truck maroon scotchbrite before doing the silver parts. moving on to the doorjambs the black had been setup for a week. i scuffed it with a maroon scotchbrite before shooting the second black base in the doorjambs. dry time was probably too short on that maybe half hour. as soon as i hit it with the silver it lifted the 2nd coat of black. i had to fix the back of the cab. so i wetsanded 320 grit and shot my black base. 2 hours later a light coat of clear thinking maybe that would held. 24 hours later i scuffed the clear and masked off for a silver stripe. soon as i shot the silver on the scuffed clear a very big portion of it lifted. thats where it sits. thank you very much for helping me diagnose this. i know this doesnt qualify as a hotrod but from researching on here i know there are ALOT of very knowledgable painters that can help me out. i am completely self-taught in bodywork and paint so theres alot of potential for errors. thanks again.
