i am going to seal this with SPI white epoxy. Should spray just one really thin coat or two coats and wet sand the next day? I do have a few sand throughs.
 
That is a really good question. I try to keep 2 coats of epoxy over bare metal for maximum corrosion protection, but it doesn't always happen. Inevitably there is a sand through on an edge somewhere that just gets sealer. That being said, there is quite a few rather large sand throughs there, and I would personally feel better with at least one full strength coat of epoxy over spots that large. It's really your call, as I feel epoxy reduced 25% would probably be fine, but 1 or 2 full strength coats lightly sanded then sealed with 50% reduced epoxy would be better.
 
Even a full strength the white epoxy doesn't cover well. So if the goal is a consistent color to spray over, then 2 coats full strength and wet sand is how I would proceed.
Now if you just want it sealed one coat reduced will handle that.
This is two coats over a similar color like your picture.

Thank you. Is the wet sand just to remove any trash or is it required since waiting 24hrs?
 
I like to guide coat and then wet sand with 600 prior to shooting base. It is the surest way to have a great looking paint job in my opinion.
Of course, I mainly do restoration work so my way is not the quickest.
 
I sprayed the sealer today. It was going pretty good but found I got two small runs and there is a problem with seam sealer in one spot. Can't see run very well in pic but you can see issue with sealer. How would you address?
