K frame refinishing and rebuild advice

On my front end i used some etch primer and some spray on paint. cleaned everything up real nice in the bead blast cabinet. Looked good but i got allitle brake fluid on it and the paint wrinkled up and got soft.

On my rear end i did a quicky cleaning job with dish soap (i had no degreaser) and then quicky wire wheeled it and brushed on some rustoleum enamel nice and thick. I got some brake fluid on it and it dident wrinkle and ruin the paint on me.

Granted the spray can enamel looked nicer but the brush on rustoleom job seems alot stronger. The best part is i bought a small can of it and ive done 2 rear ends and there is still more than half a can left! Also ive personaly never used the POR-15 stuff but ive heard nothing but good things about it.

heres the rears ive painted:
