How much rust can under-body spray stop?

They all always had drain holes, and plugs, you could use to access things. With the right equipment, that certainly could be possible.

The idea is, you fog the entire inside of the panel, so everything gets some product on it.

Unless you live by the ocean, with the exception of the wheel wells, it's only the bottom 1/3 of the vehicle, you really need to be concerned with treating.

Door bottoms can fairly easily be done through the bottom drain holes, using a $15 aerosol can, and the included extension for the nozzle.

Personally I prefer to remove any interior trim necessary, to not only spray it, but to verify it was covered properly. No rustproofer I know of, is going to want to do that for you.

Some vehicles, (usually the expensive ones), have sound deadening inside them, which is nothing more than a plastic bag, filled with rebound thread, or fiberglass insulation. They are commonly laying on top of the rear wheel housings. As well as other areas, like in the front fenders, and quarter panels. If you don't remove those, before spraying, you can't get to the metal under it.

I had the tailgate trim panel off of my new minivan, last fall, so I sprayed the inside bottom. I left it open, to air out for 4 days, and then, I put it back together. It still stunk up the inside of the van, for a month. :knockout:

You wouldn't think I could smell anything, after 35 years working in a body shop, but I guess I am particularly sensitive. :confused3:

Really appreciate you sharing your experience. :thumbsup:

Coobie, shhh! We don't want others to know we all live in the boonies and there are no jobs to commute to or towns to work in. Our cottage industry of making rust should remain exclusive, lest we lose market share of our #1 export to Illinois, Indiana, Ohio, and Pennsylvania.

btw, I bought the fancier gun & 18"(?) flex extension for FF but haven't used them yet. My gun's 'air-hose' thread is nothing like our familiar NPT or NPS threads, JIC, etc. The local Parker store here fixed me up with a BSPP fitting for my hose. It's so nice to have them nearby, .. out here in the boonies. (An auto paint/gun supplier should have similar.) tog

I guess I am more of a hillbilly yankee.I love living in the boonies way away from them thar city dorks.Ann Arbor,Detroit and Flint come to mind.LOL

Richard has ofically taken MO off my search list for "southernish" states when looking for used vehicles on c/l.
I previoulsy would not have imagined much if any salt use. (due to my ignorance of MO)

You gotta go down by James. And even then there are years he'll get more snow than I do. He's in the South Central. I'm extreme North. I can see Iowa off my back deck.

Thanks. Happy to help. :thumbsup:

Rusted steel sanded shiny bright still contains rust in the grain boundaries. It has to be neutralized before priming. Some primers have a corrosion inhibitor in them.

There is a pretty big difference in climate between where I live down here in Branson, Mo, and up north near the Iowa border. I tease Richard all the time about our pineapple and mango crops down here in the winter.:laughing:
