So I did some thin PLA prints (a zylon helmet strip) and the print turned out great, my problem is that when I went to paint it, there was a lot of warping, basically killing my print, any thoughts on why did this happen?
I used Pu Primer first, and there was no problem there, then I used varnish to apply a clear coat to chrome it afterwards, that’s where things got ugly, the culprit is the varnish, but I have no idea why.

I attached a photo showing the print without paint (left) and the one that’s all bent (right)
