first post in general section, i bought a kansas fzj80, and was wondering what a protective spray undercoat looks like. iwent to clean up the underside with degreaser and found a tar like coating on the pans, crossmember, and tank. i think with enough psi i can blast it off, but plain degreraser wouldn't touch it. do you think this is just 150k of build up, or possibly some kind of coating. i'm in az so i have no idea what undercoating looks like. thanks
