under coating

Would it hurt to spray some undercoating on the frame of my Blazer? The frame looks rusty. This is a 2000(of course it is surface it is not rusted out)

nope. it'd be fine. did it to my 95 for the same reason. looks good being black and not rust.

I used the spray cans of 3M Undercoating puchased at an auto parts store. I applied it on the frame rails as well as the wheel wells. Keeps it looking nice and black. No rust whatsoever.

just do some light sanding and get some 3m undercoating... if you have a nice cement driveway, dont do it there

Heh, since I did my BL the frame really showed it's color... (rust) I spent yesterday doing my frame with bedliner coating.... Stuff hardens like a rock and dries with a very nice texture... (Used duplicolor bed liner w/ a spray gun)

i put my under coating on in the grass. i didn't sand it and it held though the winter fine. i used black spray paint to do the wheel wells and i also painted my rear axle and leaf springs.

rlith, let me know how that holds up, ive got half a gallon of liner left from when i did my bed, and if it works ok i want to spray my frame
