Default White paint fading yellow

So three months ago I finished going through my old softail, it's a 94 or 5 Evo in a paucho frame, 5 speed, BDL 3" belt drive. I stripped it down to bare frame and changed color from black on black to Arctic white tanks, front and rear fenders and a gun metal gray frame. I used to work in the paint shop of a truck & equipment repair shop and used delfleet single stage paint on almost everything. So I stripped everything to bare metal and used a good primer and paint and was really happy with the finished product. But now the gas tanks, just the tanks are starting to yellow. The bike sits inside most of the time and I haven't spilled any gas on it and like I said just the tanks are turning yellow the fenders are a brite white still. Any body else use single stage paint?
Run into this before? I'll probably just leave it unless it gets real ugly just curious to see if any body else has seen this.


You can really see the difference between the fender and tank here.

It looks to me like it could be discoloration from engine heat dissipation because of where I'm seeing the yellowing in the pic. And also would explain why your fenders are still bright white. Since the clears in singles stage paints settle at the surface, you may be able to wet sand and buff the yellowing out. And then if you're happy with the color, I would recommend spraying a few additional coats of clear onto the tank just to help insulate the color a little more and would also give you plenty of "meat" to be able to buff it out in the future, if necessary. That's what I'd try first. Good luck.

That makes sense although this bike doesn't have but 300 miles on it since I went through it. I remember why I bought my bagger when I ride it! Thanks I'll try that.
