Rustoleum vs. POR 15 vs. others

Subscirbed.

I have been given mixed reviews on POR15 by pro's...with the cost and the mixed reviews I decided to opt out of it. After a bunch of reading it seems that every rust converter uses the same chemical which happens to be a plant extract. Use Napa rust treatment, on pitted rust areas seems to work pretty good. 10bucks a bottle and goes a long way. It also hardens really well and allows me to coat bare metal areas im working on until I shoot primer.

Interested in getting more pros take on it from off of here.
