anti-rust treatments

[koss78a]

WHen getting rust treatments done is going with DRipless worthwhile, or is it just a waste of $$$
vs getting the normal treatment that drips for a few days afterwards?

[REN69]

Oil treatments work fine, I believe Toyota dealers offer it for about the same price as Krown or any other rust proofing places do.

get the one that drips, it penetrates better as its lighter stuff.

Hey fellas,
I guess your not talking about undercoating. How does the stuff you are talking about work?

[Flashmn]

Its a wax based rust-proofing chemical, that basically coats the inside of the body panels with rust inhibitors and also removes access of oxygen to the surface.

[diver9000]

is it primarily for areas where there is snow/ice or is it a benefit for everyone to use it?

[Flashmn]

I'd do it in any case. Moisture can get in between the panels. Rusting in general doesnt start easily from the middle of the panel, unless theres no paint, they always start at the edges or welds. a car has several miles of unpainted surfaces, due to welding the process. Rust proofing can penetrate between the seams and protect them.

Is this something that I can purchase and do myself or is this one of those I should leave up to a pro?

I do it myself in the known bad areas, bottoms of doors, rockers, Back of rear fenders, i buy the spray bombs of the stuff, If your gonna get it done professionally make sure there product doesn't react with the rubber weatherstriping on your car!

The previous owner of my car decided to get it done the product used made all the weatherstriping grow about 50% bigger in size, needless to say ive replaced almost all my weatherstripping!

To add more protection get the spray bombs of undercoating get a disposable coverall and go to town, scrape out the dirt and spray it! get the back of the front fenders, especially where they go down to the rockers, also the firewall door pillar area, rear inner fenders, underside of the trunk floor around the back of the car and where the rear quarters tie into the trunk floor behind the wheel. those seem to be the bad places!

Sounds like they used gasoline or kerosene to thin the stuff. Using Dinitrol or tectyl stuff shouldnt react.

Undercoating wont last long on fenders or rockersills, as they're constantly pounded by sand and stones. Stoneguard is better option there.

I rustproof my corolla myself, but on our parents car, I'm leaving it to the pros.

Hey Flashmn, whats new? Stoneguard, what is it?
94_Rolla_Guy: When you say spray bombs, are you talking about just using the stuff that you get at the local autoparts place in a can? Hey thanks, I appreciate the input. Just trying to figure out what I should use on it as a preventative. It isnt driven in a lot of snow, everything else, just not a lot of snow down here.

[Flashmn]

Its a tough coat that withstands flying rocks, it wont spiderweb and crack open like undercoating.

As for spraycan versions, they suck, because they need to be so thin to come out of the bottle. The coverage and coating is only thin on the panel. Aircompressor and a mass-spray is a good way to do it.
Underchassis = undercoat, thick brush on is quite good too on large areas, but close to cables and lines, compressor stuff.
Wheel arches, inside floor, rear parts behind bumper, side skirts = stoneguard.
Inside doors and bodypanels = wax based rustproofing chemical.

[diver9000]

Cool, now where can I get the stuff?

[Flashmn]

I got mine from my work. autoparts stores should have it. go for dinitrol or tectyl, other ones are gonna suck. 3M blows ass, its really the worst, I put 3M and it flaked after 6mo.

[diver9000]

hey thanks flashmn. I am checking with my local parts place and the only stuff they sale is some gel stuff called "the right stuff". They dont have it so I will look elsewhere.
