Take a grinder with a flexible grinding disc.
Grind everything to bare metal.
Clean the bare metal with metal prep.
Option 1: If you are going to paint, then you need to sand with progressively finer sand paper and then prime, sand, then paint. This gets rid of the grinding marks.
Option 2: If you are going to roll or spray on bedliner, then just go for it after cleaning the metal with metal prep..

Not really grind.. just take a very thin layer off to roughen it up and get rid of any mill scale. Think of it as sanding.

This can be time consuming.... Angle grinder is the most useful tool for this stuff. I use flap disks and wire brush cups. Some areas will be impossible to reach, so don't get too worried about it.

So if I want to do the bed liner do I still need to sand/grind the metal??

Yes. Everything down to option 1 or 2.

I'm picking up my SSO sliders today. I'd be more than willing to paint them myself, but I live in an apartment complex. No garage. No available garage to borrow either. And the complex specifically prohibits painting things in the parking lot. So off to a shop I go.

I'd ask for a zinc rich primer powder base coat, and ask them to hot flock the zinc primer

This is one of the most informative threads I've read in a while. Now I know what to do when I finally purchase some sliders to save a couple hundred bucks!

1969 MGB GT. It's getting supercharged and air-conditioned.

That looks like fun! My grandpa used to have a Triumph GT6 that he let me Autocross when I was 15, and my uncle had a Spitfire, both were red and both were rebuilt by hand by them respectively. I miss that GT6!

Heck yea bro, I'm purchasing some bad ass C4 rock sliders and they don't powder coat. pRATTLE CAN IT IS:behindsofa::uzi:

I had my C4 Fab sliders powder coated. The price was $160 and I had the steps powder coated with a wrinkle surfaced powder coat while the bars are smooth... It ended up costing me more overall cuz the powder coater was an hour away. So total with gas and powder coat prob $200. Worth every penny.

And the C4 Fab sliders are bad to the bone!

It's worth the money.. but not so much if you actually use the sliders for what they are designed for. The underside and edges will get completely torn up on a regular basis.

Now, I understand that people put this stuff on their trucks for the looks or "potential" of contacting rocks... in that case the powder coating makes more sense. Bumpers are a totally different story since they don't see the constant bashing that a slider or skid does. For those, I pay to get them powder coated on my 4r. On my trail rig.. I paint everything since all the armor sees constant bashing.

If you just want corrosion resistance and don't really care much about UV protection or looks.. I've been using chassis saver paint recently. It's more of a brush on product but can be thinned and sprayed. It's very durable so far.

To add with the above about powdercoating sliders. Once you chip the powdercoat it compromises the rest of the powdercoat and makes the rest chip off and peel easier, think like peeling a hardboiled egg.
Best bet for sliders if you actually use them would be linex or rhino lining etc.

 

[Señor_Godric]

What do you guys think about using Rust-oleum Truck bed liner??? You think that will work better than powder coating???

Here is my experience with diy of my metaltech rock sliders...

I too thought I could save money by doing it myself. I thought that it would be quick and easy. Especially at the time I had a new born and I hadn't wrenched in a while on anything.

I should have listened to myself that over the many many years of being a grease monkey that paint is hard to do well. The metaltech sliders still had the milscale on the tubing as well as well as any oil left to keep the raw steal from rusting. I went through countless 1 gallon acetone bottles from home depot to try to get the mill scale off. I then resorted to soapy hot water, then tried vinegar and anything I could Google search. This took me 4 days to prep the sliders while working on a bunch of cardboard laid out on the floor of my garage.

I then bought 3 cans of primer and ended up buying another 4 cans of vht matte epoxy paint. Primer I think was 5.99 a can at pepboys, the vht paint was 7.99 I think... I also had to drive around to 2 pepboys to find enough rattle can. The acetone was 3.99 at home depot, I went through 4 cans of it.

After painting primer and 3 coats of paint I mounted the sliders carefully. The first step I put my foot on the sliders to see, a chunk of paint came off. I was pissed. 2 weekends wasted, back was sore and I spent around $80 to $90 on paint and it all needed to be redone. I thought I prepped the sliders perfectly and made sure the metal was clean... But I guess not.

I was quoted 130 bux to have them powder coated locally here in San Jose. I ultimately unbolted the sliders and dropped them off to be sandblasted and powder coating after living with rusty sliders for a year.

Morale of the story. Get them powder coated. The powder coating is way stronger than rattle can and the pros have a way of sandblasting, dipping, prepping better than you can do at home.

I now just touch up with por15 and a bit of rattle can for overcoat as needed. So far the powder coating has held up very very well.

Which shop did you end up using? I'm in San Jose and looking for a good powder coating shop for my CBI skid plates.

I used BR&F Spray Incorporated

Bed liner is good for all kinds of things. I just coated some level 3 armor plates with Herculiner to minimize spall and fragmentation.

Damn - I cant believe what some people are saying about powdercoating! I powdercoated my sliders back in 2005. They have been beat up on on rock trails, climbed on by kids, and self when loading the roof and they have lasted all that time with only touch up rattle can underneath where rocks have gouged or scratched.

Granted that the top section where foot traffic is high needs a little cut and polish from time to time but 14 years and there's no way paint would keep up with that amount of abuse.

My bumper is the same. In all that time never have I needed to re powdercoat.
