What is the best rust converter / prevention product for cars?

Question

I've used POR15 with subpar results. I see there is a new 3 step product called Rust Encapsulator on the market. Will this do a better job? I have a 1990 truck with rust in the usual places, but its just surface rust, not rot (yet) in most areas. I'm looking to stop it permanently, and was considering topcoating the lower body with Durabak (which is a spray in bedliner type product) once the rust is neutralized.

The truck was regularly "rustproofed" with rubberized undercoating by the previous owner which may or may not have helped matters. I figure the Durabak would be a more permanent form of undercoating since it doesn't flake off.

Any takers?

Answer 1

You need to get all the old undercoating off and get down to the bare metal by Sandblasting. I recommend KBS Coatings which has the most superior technologically advanced 3-step-system on the market: Klean/Blast/Seal. However, on newly sandblasted surfaces, prep products are NOT needed so you just proceed with sealing with their rust preventive paint called kBS RustSeal. RustSeal is formulated with a unique viscosity that allows it to seep deep down into the open metal pores where it cures rock hard and permanently blocks off all access to moisture & oxygen. KBS Coatings Rust Seal is superior to POR in that it has deeper adhesion ability, richer pigment qualities & unbelievable finishes, cures rock hard & watertight yet remains flexible to expand & contract, sands w/o gumming and comes in a variety of new colors...gloss black, satin (OEM) black, silver, grey, clear, oxide red, guardian green & off white.

Then I'd topcoat with Durabek or choose KBS BlackTop...their rock hard permanent automotive chassis topcoat for a final professional looking finish.

Best Rust Converter

Answer 3

That sounds like a good idea if that bedliner stuff doesn't crack and trap the water. I think I'll try that myself on a couple of projects. The last rust converter I used was "ERF" from E.R.F. Industries in LosAngeles, California 90034 PO Box 341076 which stands for End Rust Forever. It doesn't list the ingredients on the can, and I can't seem to locate the product anymore. It seems to have worked better than any I've ever used, but it is sensitive to UltraViolet radiation.

Answer 4

i've used the Kbs Rustseal alot. It's a moisture-cured non-porous coating that cures by drawing moisture out of the metal pores & air and (the reverse of other paints)...and is actually strengthened by repeated exposure to moisture. On humid days, this sealer dries almost as you're applying it...that's why they recommend application below 70% humidity. It's also the best rust protection for marine applications. If rustseal is properly applied on the bare metal, rust will never return even if the topcoat fails b/c The pores are locked watertight. Rustseal does have some UV sensitivity too but much better than others. But understand this, the rust protection NEVER fails...it just means the color may dull or sheen may matte (cosmetic changes only).

Answer 5

There is a new website called www.corrosionconnection.com that has a whole section of rust and corrosion prevention for cars and trucks. It also has a whole list of products just for that purpose! Check it out, maybe it can help you

Answer 6

Acid works to change the polarity of the metal, as that permanently ceases the oxidation process, but isn't easy or simple to use.

Need good Gloves etc.

Wash with water after.

Good primer then top coat done well should last well, that and Mud Flaps, as they work the best.

Answer 7

Back when i owned a marine repair business I stumbled on to this product called OSPHO. Worked great. I later used it on cars that i was restoring and repairing for others---and still use it now. Over 25 years it has served me well.

Answer 8
