It's had a quite a bit of time outside already, from the begining of sept of last year till the first week in nov I pulled it outside pretty much every day the sun was shining, I did the same thing this year from the end of march till now. We haven't had too many hot days yet but even on the not so hot days the paint felt very warm when sitting in the sun, I even move the car around during the day when it was sitting in the sun just to make sure it had full sun exposure. I will give it another week or so in the sun, if I don't see improvement I will probably end up stripping it. I had the mirrors off of the car when painted, they have much less paint on them than the rest of the car and that paint feels about the same as the rest of the car.
