just confirming the next step
Hello to all, been awhile.
I just wanted to confirm some things before I continue. Your opinions welcomed as always.
Restoring and am now spraying a complete unibody "tub".
Used utech's epoxy primer, then 2k100 primer surfacer. Had very few sandthroughs down to the epoxy, and even less through to steel. I've etched the steel with Sherwin William's self etch in a spray can. Can states that its compatible with all auto topcoats. Despite this, MUST I reshoot another primer surfacer coat onto the epoxy and/or etched reveals? Or another possibility, now that it's "leveled", do I need to shoot another epoxy over the whole thing before the colors?
Thank you in any regard,

If the spots where you applied the aerosol primer are small, like sanding through on a peak, I'd say just go over it with paint but for larger areas, like baseball size, I'd recommend that you go back and apply a spot of epoxy primer. I'm not familiar with the SW product so I can't say how good or bad it is but I don't trust most primers in rattle cans.
Read the tech sheets for the products you're using to find out if there's a window between the time you sand and the time you spray but I doubt it. You can probably sand long before you paint as long as you use the proper grit and the surface remains clean.
