Thread: Rust Protection

i've used a product called Fertan a few times on an earlier vehicle with a bit of body rust. its been a few years since i treated it and never painted over it or re-treated it, and the rust has never come back to life!
it smells like vinegar, is dark brown, and comes in a little spray bottle, probably about 200ml i think.
when it leaks out of the bottle and is left for a while, it ends up all sticky and gooy, so it seems to be some sort of oil based product i guess. the bottle says it's all natural with no harmfull chemicals in it. all i know is it works great!

Years ago I liked Fish-oil [but it smells bad], and then painted over the fish oil with Bitchumen paint, a thick tar type paint. Bitchumen paint was once made for rain water gutters, but now days gutters are color-bond steel, and this may no longer be available.

Also a product called ColdGal [as in galvanising] is great. Most welding workshops that I know do use this Coldgal. But it is very thick, and you will use a lot, and it is very expensive, and may not suit spots like inside of the chassis, and other hard to reach spots. Coldgal hides holes and defects as well, which is another reason why welding workshops use it.
