Sealer only, no primer?
Sealer only, no primer? Just double checking. Want to apply sealer, wet sand & then paint. Anyone see a problem w/ this? Don't know why I'd absolutely need a primer first, then sealer. However, if something is being missed here, please let me now. Thanks

It would depend on the situation. Is the body nice and straight to begin with? If the body is straight and you're respraying the same color, I wouldn't seal it at all.
If it's straight and you're spraying a different color, prep per the sealers instructions and spray. Most of the time, you have a window where you can topcoat the sealer without any additional prep work. After a certain time span, you have to scuff or sand the sealer before topcoating. It depends on the brand of sealer.
If they body is wavy or you want to ensure it's very straight, I'd get a gallon of good 2K primer and prime and block the vehicle. You can then choose to seal it a different color afterward, to ensure a better base coverage. That's up to you.

Thanks for the reply. Yah, we filled the waves w/ mud & after blocking were left w/ some bare metal, some mud & some primer; again after filling the waves. You're right though, I'm gonna re-prime, re-block & then seal for color, just to be sure that she's nice & straight.
