Painting Issues.

I don't see pics....

Yikes - if it was my project, I'd stop right there and strip the paint. All of the time you'd spend trying to sand through all of that is a big investment of time and effort. A chemical stripper would take care of things quickly and leave you a cleaner surface to repaint over. Less work, better results.

Best advice? Don't paint when it's really humid and certainly don't paint outdoors when it's raining. 

Looks like the first layer was not dry enough so the solvent in the second coat caused it to wrinkle and lift. I'd also recommend stripping the paint off and starting over to ensure a clean surface. Sanding the rough, lifted paint areas and repainting may cause issues again if the underlying paint is damaged in any way. 

Why would you paint in the rain to begin with? Still don't see any pics. :((

Thanks all for your responses and tips.
 @BlackSheepTwoOneFour: It was suprisanly a nice day, didn't look like rain. That happens form time to time in the PNW. I couldn't figure out how to add the pics to the form I think if you click on the boxes it'll take you to the pics.

I don't really have anyother place to paint other then outside, I don't like doing it in my room.

Any suggestions of a good paint striper and any tips on using it? I'm using testors enamel paint BTW.

 This is my first model so I'm assume it's not going to be the best, Mainly use it as a learning experience.

Again, thank  you all for your posts and expertice

Get a plastic tub / with lid big enough to hold it.  Get a gallon of Castrol Super Clean (the purple stuff) or a gallon of Simple Green, both are under $10, at the local Wally World or equivalent, or enough brake fluid at a local auto parts store.  Cover and soak for a day or so, then lightly scrub with an old toothbrush.  May take a couple of soaks to get it all.  Wash in a mild dish soap to clean all residue and air dry.

Only do in a well ventilated area and don't leave the tub and fluids indoors.  Don't mix any of the above with each other.  Use as it comes from the jug.

The others hit it right on.  Breaking the film on enamel will cause it to lift and wrinkle when it is not fully cured, take it from an old auto painter.  Been there, done that, and have a few shirts in the drawer to prove it.  And they were lots bigger goofs.

Good luck on getting it off and ready to reshoot.  Yep, learning experience for sure.  Sorry it happened to you, but we all have paint mishaps and get better at it in time.

If you use the Purple Power stuff to strip the paint, be sure to wear chemically resistant gloves or the stuff will go goofy things to your skin. That's a learning experience in and of itself - wear gloves!

Good advice, Knight.  I've got 40+ years of grease, thinners, paint, dirt and whatever else ground in.... I think I'm permanently water and fluid proof.

Get a box of latex gloves.  Not only for cleaning, but use them when holding pieces when AB'ing them.  Makes life easier in the long run.
