I have completely primed fuse & all surfaces on my TGA Interceptor.I however have 1 stubborn section on my left wing approx.10x6 inches in diameter that for some reason keeps giving me the cracked appearance & also stays tacky to the touch.I have tried sanding it back down twice to the glass again then repriming & I still continue to get the same effect.I guess somehow I got something on the area at some point cause its reacting.I need some help as the best way to clear the problem up,a agent or something.My Interceptor is all done except for this final primer prep & the ppg paint job..I will be painting it candy red with white bottom(navy aggressor scheme)

This is gonna be one very light jet..With radio installed,powerplant in,retracts,brakes & battery its tipping the scales at 8.5 LBS.I realize its not painted yet but its should finish out at just under 10LBS it looks like.Watchhhh out Joey,I am coming after your starfire bud LOL ..
thanks in advance

go to a autobody supply shop, get wax and grease remover. follow directions on bottle. this should cure your problem with "ORANGE PEEL". i have had to do this sevral times on various projects. the last one was a wood hydro, i had to paint 3 times to get perfect results. the last time i used wax and grease remover and it turned out like glass! hope this helps and good luck. use after priming and sanding. last thing used on surface b4 painting!

Sounds like amine bloom. It a chemical reaction to humidity and low temps during the cure. Here's a link with more info

You did not mention the primer that you are using, the surface that you are painting over (epoxy, or polyester resin) and how you cleaned the airplane.

If you are using the PPG K-36 primer, clean the surface first with DX 330 wax and grease remover. Let it dry, you can accelerate the drying by using an air gun. You might try spraying several very thin coats of the K-36 over it after cleaning very well. Clean it again between coats.

Is it possible that the glass was not fully cured before priming?
