Everyone will have their favorite. I've had the best results with Free All. Available online only as far as I know.

You could apply heat in the thread area. What could go wrong? LOL. If you go with heat fill the tank with water through the petcock port to exclude the oxygen.

I picked up a set of KJ aluminum tanks with caps on them. However, I cant seem to loosen the caps.
I've tried Gibbs Penetrating oil from the outside and inside but still can remove them.
Any suggestions ??
Thanks
