Making sure upper Control Arms are not seized.

I loosened the upper control nuts. I was able to spin the bolts. Camber? Moved in and out both sets both sides. Do I need to run the nuts out and try to tap the bolts? I want to paint the engine compartment before dropping the motor and transmission but I don’t want to have to heat the bolts if they are seized and ruin the engine compartment paint. Can they be seized if I can move them as much as I have with the wheels still on?

It should go to my fabrication shop late next week. For some Sheetmetal work. I have it prepped for him.
