Hi fellas ....interesting discussion...as we all have to deal with the dreaded rust in Bedfords.

Have any of you guys had any experience with Pour 14 the French epoxy rust and paint treatment?

I've heard that its pretty amazing.

Cheers

We did my mates Pontiac in POR15, is meant to like being put on surface rusted surfaces. It went on well, self leveling ... but a month or so later it peeled off in sheets. The rep for the stuff came out and had a look and reckoned he'd never seen that happen before, gave us full replacement but we didn't end up using it again.
Have heard similar stories over time but mostly good stuff. is very expensive though as you're meant to use the pre wash, the POR # then their post wash or primer

POR15 isn't UV stable, better off using KBS. Ive used KBS diamondfinish clear over PPG base coat...awesome. This time trying the KBS blacktop as a top coat.

I have just started using the KBS system, and so far the results are looking good, have only done some small parts so far just to test, but will properly use for the whole under body and inner guards

for the underbody of my custom van I used what was being sold as roof paint, truck drivers started using it so now has been re branded, can brush or spray it on, self leveling and has a gloss (ish) finish, is water proof, able to handle all weather conditions... I put that on and undersealed over top

Hey Busy, roof paint, is that the black bitumen paint.

Q. There is a spray on material they use for truck/ute tray floors, could you use that underneath a vehicle ? or would it be noisy, or an issue with rust.

no not the bitumen type, this was grey and went on like wet rtv. The tin doesn't have any brand names or anything - I think they poured 10 litre buckets into 4L tins.

There are several spray on liners on the market, the more basic type is called "stone guard" or "stone chip", very good to put on guards around the bottom of wheel arches and on front panels etc. You can use it underneath but it doesn't have the sound deadening properties of underseal, plus stone guard should be applied over a painted surface, then again so should underseal. Why you ask, 2 layers are better than one, if a stone chips the underseal it still has a layer of paint to stop the water getting in, overwise if the underseal is over bare metal the water can get under the underseal once waters gets to the steel
