When I talked to NH Oil Undercoating they said that just about every vehicle 6-7 yrs or newer had enough drain hole to get everything without drilling. Any thoughts?
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:
