Hi tobyS...Nice truck AZK9. Are those 9.00 or 11.00 tires?
If your paint had long enough to set up and isn't bleeding from the rain by now, I doubt that it will. I painted a test area on an M105 and first it rained then snowed and it still hardened up fine.
The tires are 9.00 in size. They're T-Hawks that are in pretty nice condition.
I think you are correct about the 'setting up'. We just finished in time for the paint
to 'shield' itself from the damage that the rain could have caused in the event the storms
had come earlier. We were very lucky! No bleeding and none washed off!
