Your good. I'd sand and feather the edges and put on a full Layer of CSM followed by two full layers of 1708 6 to 8" overlap.
I always recommend using primer that's compatible with the final finish coat of paint. They work together to promote proper adhesion. Have you given any thought to what paint system you'll be using?
