I'm not familiar with Eastwood's spray. I've used their internal frame coating spray. Actually I used it on a 914 rear lid between the inner structure and outer skin.
My suggestion would be to contact them and ask. They have a on-line chat function that worked well for me when I asked them about dry time for the stuff I used.
Thank you Rick.. Apparently they don't recommend using etching primer if you used any other form of etching.. Good to know!
