Epoxy is not a primer. A larger tip would be for heavier bodied sandable primer. In the old days we used epoxy for a sealer with a little thinning and to protect bare metal .
So this is contrary to what I've seen, in that I thought the bare metal coats were done straight 1:1, no thinning, two med-wet coats. Do body work, spot spray as you go along, then high build, block sand, then seal with epoxy again, "thinned" to lay down a smooth layer, then BC/CC.
Is that not right? Variations for different scenarios?
