Have an obs and I have stripped her down to the frame minus the cab (to big for me to move by myself). Not looking for a show finish but I would like it to look uniform. Having trouble getting the Aerosal Rubberized Undercoating to stick. I have used 4 brands and after a few days curing it still chips/scratches very easy. Any suggestions? http://i314.photobucket.com/albums/ll424/crzy1c/1997%20Z-71%20project/DSC01690.jpg very easy. Any suggestions?

We have a product called "HAMMERITE" it is a rust proofing paint or spray.It bonds to the metal.You do a rough first coat,then re-coat between an hour to 8 hours after you go over with a second final coat,the final coat then bonds to the first and any brush marks disappear leaving a smooth shiny surface.It comes in SMOOTH or HAMMERED finish,and last 5 years (what it says on the tin)
I'm not sure if it's sold over your side....have a look...www.hammerite.com

that rubberized undercoating spray is complete shat. It's meant to go over primer, but it wears off over time.

I used 4 cans over rustoleum primer on my fuel tank in February (upgraded the pump). Just wanted to seal the mild surface rust and test the undercoating before using it elsewhere. My evaluation is the undercoat is a complete waste, wish I would have just done a few coats of industrial paint.

You're better off go with one of the POR-15 variants as a base. Just be sure to use an intermediary coat and then paint on top.

POR15 is where it's at. That stuff spreads really nice and lasts forever! :read:

The POR-15 can Iuse it over what I have laid down or should I strip to bare and start fresh?

It's made to go on metal so if you still have that rubberized stuff on there I'd get it off. Then spray on some Metal Ready (sold at www.por15.com) on the surface you're applying the POR15 to and then go to town.

Try undercoating in a professional spray gun i did that to my frame 2 yrs ago and its still there, or try a frame paint which is basically a thicker more durable paint
