Did you POR the inside of the patch as well? I've also been patching this summerl... let's just say my task was a little bit more extensive than yours! I think it will be fine.
Another thing I recommended is using a black seam sealer on the inside of the patches over top the POR.
After not being able to find a driver side rocker panel I 'simply' made due with cutting out the bad spots and fabricating all new patches. It took about 18 - 20 hours over 2 weeks but it's nearly done. I'm pretty proud of how well it's turned out, I'll have to take some pics shortly.
Performance one step at a time.
