They sell a sprayable rust convertable but I can't find any outside reviews for this stuff. Also, MSDS says not to breath vapors so looks like it will need pro install/application and not DIY homeowner.


This is a latex solution, not liquid U235 or your local vitamins, I gave the owners a bit of common sense, in that they would use to proper protection.
We are not all as stupid as the internet would have us believe.

A tyvek suit from Home Depot and a paint mask with goggles should be all you need, it is like the interior latex paint you use to paint houses. It ain't some thing you like to get on ya.

IT is a good idea to scrub the area, I'd use ZEP"s Purple Industrial cleaner and degreaser, Soak it down then a pressure washer get it as clean as possible prior to coating with rust converter.

Be careful The ZEP industrial cleaner is a very strong cleaner, don't breath the fumes, or get it on ya. But it will cut grease and grime better than anything I've seen before.

Phosphoric acid is the active ingredient in all rust inhibitors and can be bought by the gallon in the paint department of Home Depot. Using a shop cleaning spray gun you can spray the undercarriage (staying upwind) yourself. Driving in a heavy rain is a good way to clean the undercarriage and once dry I would spray the bottom with Fluid Film using the same cleaning gun. You can buy FF by the gallon.


This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.

I'm no chemist, but there is a difference between a rust inhibitors and a rust converter.
