2K over sand throughs?

Have my car in poly primer(quicksand) over SPI epoxy. While block sanding I have some areas of bare metal. I thought I had it straighter than it is at this point. Is it okay to use the 2k over these spots? The largest is about the diameter of a golf ball.
 
Yes it will be fine... Its always better to use epoxy over bare metal, on a spot that small I would not bat an eye.. I dont hardly think you are going to lose any adhesion over that spot.. The benefit over the 2k with epoxy is corrosion protection.. Now if you have something chip there it would be better with epoxy on it, but again, I dont think this is really going to be an issue..

People used to strip cars to bare metal and cover them with 2k years ago all day long.. Epoxy would have been better, then 2k, Im just giving you a reference point is all

If your doing a resto, then you can spot those area's in if you feel the need with 1 coat of epoxy, wait an hour and then apply 2k.. Most will tell you this is the best option, and it is!!! Im simply telling you if you didnt want to, the paint wouldnt fall off your ride or anything
 
If you have the epoxy, and a little free time, there is no reason not to spot those bare areas with epoxy.

I've seen 2K have poor adhesion over metal more than enough times, I don't use it that way anymore.
 
Thanks for the info. I do have the epoxy and I don't want to rush through this. So, i'll spray epoxy over the bare spots. I love spraying the epoxy anyways!
