I am thinking of ordering a quart of RUST PREVENTIVE paint to touch up the undersides of all my vehicles.
Apparently there are many options such as POR, Rust Bullit, Eastwood etc....
Does anybody have experience with these and which would be most recommended? Thanks

There has been a great deal of support for Krown on this board if I'm not mistaken.
 
Frequent application of plain old used engine oil will work.
This requires work and attention! Depends on how cheap you are!

Common Rustoleum can work very well. You don't need a perfect substrate, either. Use their special primer first and it will work even better.

POR is a known very good product. I have heard Holy Grail stories of Krown, but it is generally not available.
 
I haven't seen Krown anywhere either. It seems to be popular in Canada.. I may use Rustoleum Rusty metal Primer topped with regular Rustoleum paint to save on shipping cost.
 
POR-15 works best if you use their degreaser and do it in the dry. And forget about re-coating another area once it dries. It hates sticking to itself, except when you rough it up.

It's a 100% Canadian owned and operated, so I guess they haven't expanded into the States (at least the ones that get snow/salt etc). www.krown.com

I just had my yearly application done a few days ago - this stuff works and works well, and is one of only two rustproofing services recommended by the APA www.apa.ca who state

"Annual rustproofing. The product is an excellent penetrant. It outperformed all similar products in ASTM durability tests {ASTMB-117}, and is used by the military and large commercial fleets. Krown recertifies technicians annually to maintain quality and provides excellent support from the head office. The application is thorough, with holes drilled using special bits to minimize damage. Most competitors cover about 10 areas on the vehicle; Krown does over 25. The cost is $100-$130 per year depending on the vehicle, and resprays are guaranteed against price increases for as long as you own your vehicle. APA members receive a $5 discount off the regular retail price of a Krown application. The Krown warranty covers seam or crevice corrosion, and is honoured across Canada."

Anyway, if one lives close to the border, it might be worth one's time to drive to a Krown dealership and get sprayed.
 
Man, I want to do the Krown thing bad, but add the cost of the border crossing and passport.......

Any ways to not have to get a passport???
 
It doesn't cost you anything to cross the border does it? Just gas I guess. But I guess you would have to get/renew your passport?

I just sent Krown an email to see if they have plans to expand into the U.S. You can start a franchise in Canada...wonder if they'd do that for an American?

Rust Check & Krown are both fine. The Krown is a slightly better price.
Clean the underside as best you can first, give it a couple days to dry. Then ask them to soak the heck out of it. I've seen some spray it as if it's liquid Gold.

Krown's T-32 and T-40 spray are quite thin liquids, something like the viscosity of ATF (it appeared to me). Spraying too much on wouldn't accomplish anything as the excess would all run off.
 
Fluid Film is available here in the States. You do have to DIY it on your car. A case of 12 cans is $90-95 shipped. 3-4 cans will do a small car.
 
Are these products such as Rust Check and Krown an oil type product? Or are they and undercoating product?

I know what POR-15 is and I know what EXTEND is and have used them. Some of the products mentioned such as POR-15 are designed for restoration projects to keep rust at bay. And these resto projects will never see harsh environments. I have tried similar products on daily drivers with proper primer/paints and nothing stops rust, only slows it down a bit. Especially when driving in the salt laden winter here in the north.

I can't keep a daily driver much past 16-18 years with out the rest of the vehicle falling apart and replacing brake lines, P/S lines/hoses, transmission lines and fuel lines/tanks. Then after I have replaced all of those items, the strut towers rot out or the floor boards and rocker panels rust through or I get water in the trunk all from rot that I can't control. I've tried spraying rust control products everywhere I can in order to keep rust at bay. Maybe 18 years is good but the amount of winter salt used here in the northeast is unbeleivable!

Even thought the power train is still in decent shape with several hundred thousand miles on them, the rust puts the vehicle in it's grave.
 
18 years for a car in Rochester is great! I'd be thrilled if my rusty Buick made 18 years...I'll see how Fluid Film does with that. Also the areas on the underside that were POR-15'ed this summer.

Fluid film is good stuff - really expensive. It's a lanolin product. You can buy it also by the gallon but then you'll have to rig up your own sprayer. Probably way cheaper by the gallon than buying 12 aerosol cans. I haven't found that much difficulty buying this in retail stores.

If you're talking about Krown (you should maybe click 'quote' before you post), it's "petroleum based" per their website.

RustChex is available in some parts of the U.S. Google it and check. Also If you happen to be in the southern Michigan area South Bend Indiana has a RustChex dealer.
 
Anyone know if Fluid Film can go over Amsoil HD Metal Protector without removing the Metal Protector?

I have considered RustChex in South Bend. It seems like when I googled Krown vs. Rust Check in the past, Krown was the hands down "anecdotal" favorite.

I have seen some wild claims: Rust Check contain more solvents (implied bad), Rust Check turns acidic???, etc..

Comments?
