Crazing

[MisterCinders]

Trying to repaint my seat pan. The primer keeps crazing on me. Cannot tell what is causing the reaction, and the cracks are deep enough to require sanding almost all the primer off to reshoot.

What to do?

try cleaning, or cleaning again with mineral spirits, let dry for a good hour or so afterwards, careful handling it, it's usually from not being clean enough, trapped oils, try and sit your pan in the sun if you can,the suns heat helps me quite a bit with the primer adhesion. Might try another can of primer, might not be mixed well, or bad can.

If you didn't strip the seat pan all the way to bare metal, sounds like the primer is reacting badly to what's on there. It may have been repainted in the past with an enamel, and you're using lacquer primer or something like that to cause the reaction. I'd probably strip it bare and start from scratch.

It's an ABS pan. Ended up sanding it down and re-priming. So far, so good.

Little fingerprints and pits in the undercoat always get me. I make sure to hit everything with a good coat of 90% rubbing alcohol and let it dry for a half hour....then its all about mist coats.

Yeah, I hit it with plenty of mineral spirits and gave it ample drying time. Then went with very light mist coats, watching like a hawk for any peel or crazing.

You should be in the clear. Dont be affraid to wet sand 1000 grit on the primer before paint if its not perfect.
