Rust on lower quarter

[michibronc]

I was wondering if anyone out there has good advice or sources of information about using the roll / spray on bedliner on the lower quarter of a bronco to conceal very light rust and hopefully prevent new damage and rock chips. I don't have anything even close to "rusting out", just some very light surface rust that I think I could get off with a sandblaster and prime. It seems like it would be pretty tough and sharp looking if it's taped off nice during application.

Just wondering if this is a good option or not. Any feelings one way or the other?

if its light surface rust. first sand it down ( Both sides) then you would want to POR-15 it. POR-15 is a paint that is used to stop rust / prevent it. then if you feel so inclined you can spray some rubberized undercoat, it may be hard to apply paint over that though.

Thanks for the advice on the POR 15. I looked it up and it seems like a pretty good product. The POR 15 website says you need to topcoat it if it'll be exposed to sunlight. There's a product called "Grizzly Grip" that seems to come in a lot of colors. The website is http://www.grizzlygrip.com/guard.asp# My hard top is deep blue and is sort of textured like the grizzly grip is. I think the grizzly grip would be a good, durable match. Do you think that the POR 15 with a paint top coat would be better? If so, is there a specific chip resistant paint that you would recommend (if there is such a thing)?

Thanks so much for your advice. I'm kind of new to the whole body work scene.

well, it depends what you would be doing with your truck. If you plan on off-roading and mudding then i would highly recommend that grizzly grip or similar product. ofcourse if you dont plan on doing that then a simple coat or two of paint over the POR -15 will work fine. Just make sure you do both sides of the panel. mine actualy rusted from the inside out, so make sure you do it right the first time.

IF you paint over any rust with a bedliner material, it will not prevent the rust from continuing to eat thru the metal. Products like POR-15 require some prep work, but are ideal if you don't have holes throught the sheetmetal. You can paint over the POR-15 if you so desire, just be sure to follow their directions. Another good product is Rust Bullet. I wire-wheeled all of the surface rust off of my 84 frame, primered with Rustoleum, and sprayed 2-3 coats of Dupli-Color spray-on bedliner. It has a good shine, but will not protect from repeated trail rash over time. Still a cheaper alternative than those others which run about $80-$100/gallon. I wish I had sandblasted the frame, it would have saved alot of time. I would not sandblast any of the body or sheetmetal, as it can be too harsh. Most body shops use a media blast, which contains walnut shells or similar. That will remove the layers of paint, any body filler, etc. without warping the thin sheetmetal. JSM84

Good advice - Can you media blast using a traditional sandblaster?
