How screwed did I get on this 2012 Tacoma?

This is what the Military also uses, RP-342, its a wax based coating. It seems a few of the products you folks mentioned are similar. Corrosion Free looks interesting but I'd like to see more feedback. Wollwaxed is Lanolin like Fluid film. Wields are weakest and these coatings would really help. Apparently I can use Kerosine to remove goo like black undercoating the PO put on. I'd like to at least clean, wire/abrasive brush (maybe also sand blast it, red gun in pic) and then Rust Bullet or Por 15 the bottom of the frame as it sees the most exposure and has the only real rust (pic below). And heres the box frame in the front, looks good. All your inputs been so great.

 

12 years from the first in-service date.

 

Not terrible. Wondering if that is Toyota's undercoating on there?

 

Absolutely not.

 

Oh I really need to stop regretting buying this from such dumb ass. Walmart 8 dollar a can. And I cant get it off, it sucks. I want to go back to the guy and head butt him.
