Rust Inhibitors

[gorillamel]

Simply because I am somewhat (to a degree) cheap, I am not powdercoating my bumpers. The good part of this is that I save money. The bad part of this is that by only using spray-on bedliner, rust begins to show through it causing me to grind off the rust and repaint.

I've been considering after grinding off the rust to put a rust inhibitor on my bumpers and then spraying the bedliner on there. But I have to admit some ignorance on rust inhibitor products. Some of the sound like they are the last thing you put on a metal surface, i.e. do not paint over them. Whereas others, are putty-like, etc. Does any one have any experience and recommendations on these products?

So far I've read up on POR15, WD-40, Rust Off and Rust Cure. Still clueless.

rusto makes a spray on prevent rust primer, that's why i use on my metals. has worked fairly well for me on all my trucks, rims etc.

its like 6 bucks at oriley (sp) used to be shucks, anyways prep prime paint you should be good until it gets scraped off, it says you dont have to prime but i did on my skids cause well the more coats the better i figure down there.

From reading, POR15 would be the Cadillac of paint to prevent rust, expensive. I do not know about painting over it though.

X nerds unite!

POR15 is bulletproof! I've used it on my rear bumper and one of my skids. You can paint over it after it cures (which can take up to a whole day depending on atmospheric conditions). It also does expire - it'll start curing in the can. I went three months without using it and there was a 1/8" thick layer of cured POR15 on top that was a huge pain to have to cut/bore through. It's supposed to be toast within six months of opening.

For bumpers just make sure the surface is really clean... Use acetone and spray a good primer over them before painting with Bedliner... I did this to my front bumper and have no issues... Didn't do it to the rear and the rear is orange now lol

POR 15 gets all kinds of good things said about it on the other forum.

Slight threadjack- I need to do something to my sliders, the bottom is already rusting pretty good since they get scraped so often. How often do you guys recommend doing something about rust, and how do you go about touching up rusting powder coat?

KBS is another brand. I'm told it was created by the same guy that created POR-15. He left the POR-15 company for some reason and created KBS. It's not as expensive but I've read great reviews. Comes in several colors and coverage types. I was planning to use some this spring after the head gasket replace.

 

[gorillamel]

Thanks for all the suggestions. I agree POR15 is hella expensive. My bumpers did not rust too badly until winter with the salt mixed in the water = lots of oxidation, ugh.

I'll look into the KBS and Rustoleum. Figured I'll play up the "I'm a girl" part at the auto parts store and ask for help. Once I decide, I'll let you all know what I choose and how to use it MEL style, haha.

 

[ThePlasticOne]

If you go POR15, just use as much of it as you can at once (do your frame! Do your wheels! DO EVERYTHING!) because, like I said, it will eventually start to cure in the can and be a pain to deal with.

I gotta redo my skids this spring, I might have to try KBS out - digging that Guardian Green.

I would think you could have it powder coated cheaper then por15

 

[civicjoe]

I would think you could have it powder coated cheaper then por15

quite possibly true as you still have to paint it after you por15 right?

I've used kbs and por 15. Por 15 is not very costly I buy the tiny little cans off ebay and use as needed. Little goes a long way. Kbs is pretty decent as well however not near as smooth or uniform in color. I've bought several cans of kbs some black some silver the silver color was very blotchy. Black can was pretty decent. Both por 15 and kbs are ages ahead of other hardware store paints. Duplicolor basicly washed off with the winter salt spray. However, both kbs and por 15 require a normal top coat color as neither are uv stable I use a duplicolor rattle can. I can say since I repainted my bumper 2 years ago with por 15 that the rusting has slowed down dramatically. Its only rusting in certain areas of the bumper like the edges or other area which the paint is easily worn and wind whipped. Rather then having to completely redo the bumper in the spring I just rerattle can. Powdercoating is the best hands down option for midwest winters. My shrock stuff only rusts where its scratched by rocks thats it. If it wasn't so much money to have done I'd do my rear bumper. But my quote was upwards of $250 by the time they blasted it and covered it.

I bought a small can of P15 when I did my fenders. It was easy to work with but like others said use it or lose it. I topcoated with herculiner which needs to be used when you open it.

 

[Silver dude]

I would personally not recommend a bedliner material for wear items like sliders or other armor. When it gets laid into a rock the coating gouges horribly. Its rough texture holds on to salt and rusts like crazy. Its hard to recoat as you can't easily remove the rust. A smooth coating repels water and mud if done right and as a result stays clean and free of problems.

^thanks for the info!

I shopped all over town looking for rust inhibitors. Could not find a single can of it anywhere, including Lowe's and Home Depot (they did not even know what POR15 was). O'Reilly's does not carry it any more here, either. Ugh.

 

[ThePlasticOne]

No, POR15 is specialty stuff. Hard to get it even at a big box auto parts store. I got mine from online from Eastwood, which had the best price I could find at the time.

Your best bet locally is to find an auto body supply shop.

Also, before you pull the trigger on the first POR15 you find, you don't need very much of it. I got a pint and only needed half doing three layers on my skids and rear bumper. You better be doing the whole truck if you buy a gallon!

 

[gorillamel]

Well, simply b/c I don't have time to order stuff online and wait, I went to Home Depot and got "krud kutter" which is a rust remover/inhibitor (or advertised as such). So far it seems to do a decent job removing rust.

Test piece.

How it dries. Gotta wait 30min before adding second coat as needed.

Then what are you going to paint it? bright green?, i wouldnt bedline it again,i think they are right about it carrying what ever crud sticks to it,

 

[gorillamel]

I put black enamel on there. Unfortunately it is high gloss since Home Depot did not have matte. I ran out and put bedliner on the skid plate. Doesn't look very pretty but its functional for my roadtrip tomorrow. I'll touch it up next weekend.

For those that live in the rusting areas of the Nation...

Has anyone attempted to rust proof the frame and underside parts that rust tend to spread to?

Now that the weather is nice it seems a good idea to do something.
