Undercoating in a can

[MaDMaXX]

I don't suppose you have a good US distributor?

*Edit - actually, looks like you can buy online from them directly - however the product doesn't say anything about dealing with rust on the surface, it's very much a protectant for where there currently isn't a rust issue - ie. spraying directly where there might already be rust, it doesn't do anything for it, like Fluidfilm does.

I use this. I can get it for about $5 a can. Much thicker than Krown and creeps just as well.

My Hyundai Accent came with what looks like truck bed liner sprayed on the bottom and then painted body color. 95% of it is still there and in great shape after 9 years. The Genesis Coupe came with the waxy type and 50% of it is gone after 7 years.

That's just a factory undersealant, it's normal.

Rustcure doesn't look to be readily available in the states either

Canada gets all the best stuff.
