    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Crazing

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.
