OK... Applied PPG SX1071 Etch, Then DLV 8005 2K primer. Now wet sanding with P600 and got thin enough to see the etch in spots. I will also need to apply some glaze in a couple of spots.

So... do I need to apply another coat of 2K primer and sand again before sealer or can I just go straight to sealer and paint? Is that trying to short cut things. I am using DLV 8085 true sealer and then soon as flashing painting color.

A lot of money.

I would have wiped on some DX 520 SG metal conditioner then rinsed.
Sprayed generic 2K primer. Sand. Respray 2K primer on panels I cut thru. Sand till flat.
Sprayed Base coat. then Clear coat.

I don't use sealer because it adds an extra layer of texture and dust.

I would not use any glaze unless it has a catalyst. Can't you just shoot the slightly low spot with 2K primer instead of the glaze?

Since you cut thru, you can spray the cut with sealer to see if edges lift. If edges don't lift then shoot your sealer. Closely inspect sealer for lifting pre base coat. Check for lifting again post base coat.

On panels that you repaired with glaze/catalyst I would reshoot 2K.

Hmmmm... No sealer because of texture? Don't take this the wrong way, you have been very helpfull, but the cost of the etch and primer is not a concern. It is an investment to making sure the finish is good. Lift I don't think will be an issue. The sealer I think is aproved for right over the etch. I will have to check but I am pretty sure. I need to use glaze and it has a hardner. It would be crazy to try to use the primer for the small imperfections that are left. Sorry... I apreciate your help.

I used to shoot epoxy followed by 2K.
I mostly quit using the epoxy because it sometimes causes more problems than it solves; there are cases where I still use epoxy.
It doesn't seem like epoxy adheres to metal better than 2K primer or 2K filler.
I like to minimize products on substrate to facilitate repair down the road.
BC can lift the DP epoxy if proper film thickness is not maintained; So be careful when you cut through.
