Outlaw I believe uses por15?

 

[DEEZUZ]

He recommended me to Monstaliner which is what I used underneath the super duty. But fluid film works magically just needs reapply

This I believe NEEDS rust to adhere. Maybe ilikemtb999 said something about a product they have now that doesn't....?

And for any channels or rockers that you can't Getz you need to pick up cavity wax from 3m along with their applicator tubes that spray deep into pockets

Unsure on that. It needs rust/rough surface otherwise it’ll just peel off. I’d do monstaliner or lineX if you’ve got the cash. LineX is pricey

I'd look at eastwood and get their DIY stuff. Plenty good for what you're doing

I'm hesitant to use Line-X stuff. Did my bed with that and less than two weeks later the shit was peeling/chipping off from extremely light use. Like sliding a cinder block on it. The location that applied it is now closed so I think they just did a shit job on everything.

 

[Bob Kazamakis]

I’ve never seen actual LineX do that. I’ve seen shitty knockoffs do that.

Its all about that prep, that prep...

So far my herculiner is holding up though I expect it to flake at some point.

POR-15 is a good base layer to apply directly to rust. I wouldn't use it as a complete coating as it gets dull and cloudy over time. If you don't use the correct formula it will also flake off of any area that wasn't rusty.

MONSTALINER is a great product, I use it on my trucks.

For frames I use the Eastwood frame coat. That shit's tough.

 

[EmersonHart13]

There it is, been a while since you posted this and couldn't remember what you preached.

 

[Outlaw]

Personally, I wouldn't use a coating like Line-X, monstaliner, etc on the underside. I use that stuff on the rockers/cab corner areas where you want the actual protection of the rubberized coating. For rust prevention, I would go with fluid film or some sort of petroleum-based coat that is hydrophobic.

This is the paint match Monstaliner applied on my F-350. The truck had rock chips and some surface rust starting on the pinch welds. I did this to everything exterior facing, and then had a petroleum-based undercoating done to the underside of the truck. It held up very well, just sold the truck and it looked good as new. You can see the black undercoat in the last picture.

This is what I use...its legit!

 

[Outlaw]

Or if you're cheap and have a gravel driveway you can just use 1:1 used 15w40 and diesel fuel lol

I wish I cared enough to do any of this.

My biggest gripe is looks on the herculiner. I know silly but any weight on it and that rubber squishes down and looks like shit forever. Mine has been holding up on the floors of the cucv for like 7.....ish years? 6 maybe?

Who applied the petroleum based undercoat Outlaw ?

I'm not that good at practicing what I preach... I also don't keep shit long enough for it to rust usually lol. I do the oil:fuel trick on my plow trucks very haphazardly in the fall. Front frame, wheelwells front/back and rockers/cab corners. I ain't laying underneath the shit doing it, just a quick once over with an old spray gun.

I did the monstaliner on my 6.7 because the pinch welds had surface rust and looked like shit. I have this weird mentality where a vehicle that's starting to rust is literally garbage. I either own perfect stuff or rusty stuff. There is no middle ground lol.

Spraytech in Fox Lake. I don't remember what the name of the coating was off the top of my head.
