Question,
Very new to this, I’m currently working on a 97 chevy silverado extended cab, emerald green. I used 2k urethane primer surfacer!
High build, did prep work on body, sprayed it on, no runs.

My real question is I’m sanding with now with 400 /600 to get to a smooth finish, I’m burning through in some places showing the old factory paint, but no metal is showing any where! Is this a problem for me when I do start my base coat,
(Will it cover these areas alright)?
Before I do this what is the best way to remove all the primer dust, what is recommended?

Thank you guys and gals for you feed back!

Thank you for allowing me to be part of this forum!

Rick

To save expensive cleaning products for when the are absolutely needed, I first blow the panel (s) off with compressed air, then wipe down the panel (s) using SprayWay Foam glass cleaner. (Thank you Texasking). This removes the sanding dust like a champ. Then I use this prepping method outlined by SPI member Chris Hamilton.

I noticed looking at your pictures that your sanding marks are in a straight line. Sanding should be done at a 30 to 45 degrees one direction, then 30 to 45 degrees the opposite direction. Allow the sandpaper to do the work, not your muscles.
 
For the most part I’m doing it that way!
Your right it does take less effort! I do appreciate the comments for sure!
Lot to learn for sure!
 
If you put base coat on without sealing with the epoxy per Don's advice, you stand a good chance of wrinkling the thin edge of the primer when the solvents in the base coat go on.
 
Thank you guys for the advice! It’s well taken! I believe I will spray epoxy sealer!
I certainly don’t want to undo what’s been done already! So should I just touch up those areas only!

Very useful information. I was wondering the cause and effect of not using a sealer.

Now I know.
Thanks,

Sealer is the seatbelt of the paint job. You don't need it but you wish you had it when needed.

That's a good way to look at it now that I understand the cause and effect. Though I sprayed sealer for the first time on the English Wheel, 2k sealer 4:1:2. I was throughly amazed how flat and even it sprayed. It actually put my fears to rest when I seal the Barracuda with epoxy 1:1:25%. I was going to go 10% but my confidence level is much higher to try 25%.
