While filling dings and dents in the gas tank, I applied a few guide coats (primer applied with the intent of sanding all of it all to surface level, which will leave any high or low spots easy to identify) and was relocating the tank on the painting table, at which point the worn out (unknown to me until this point) seal on the gas cap let fuel leak out onto me, my clothes and the tank.
The raw primer was immediately bubbled and lifted off the paint underneath.
Gas and paint not playing nice with each other. Not a big deal, not totally shocking but.. wow.. if I spend all this time painting a tank, only to have my first fueling mishap (and it will happen) bubble up all the paint.. I’ll be sad.
Here is the good news (I think). What happened is perfectly normal. I don’t have the ‘wrong’ primer, I just need to be careful with raw unsealed primer around fuel. The paint shop where I’m buying supplies indicated that the rest of the guide coat would likely have been damaged by the spill and I should be sure to sand ALL of it off, then re-prime when ready.
