I block sanded up to 400 grit on my 54 cab, but at the seam were the A pillar meets the cowl I sanded thru to bare metal. I am close to painting the cab but I wanted to address this issue before I proceeded to paint. How would you move forward in respect to the metal brake thru?
I would shoot a little more primer on that spot. Then be a bit lighter on the sanding.

I’m currently taking a body shop class and we discussed burn through. As the other posts said, just re-prime and go easier on the sanding. For burn through it’s common practice to touch up the burn through with a rattle can if you only have a few small spots. BUT, TO GET PROPER ADHESION it must be the same manufacturer and type of primer. For the work I’m doing on the bed steps of my ‘55, I was able to get the same Nason primer in both a quart and rattle can from our local Kemperle Inc distributor, for the situation that you’ve encountered.
