Bedliner on Plastidip vs primer

[derian06]

I'm going to take all my plasti-dip and either spray bedliner over the pasti-dip or peel it prime it and paint it with bedliner. Has anyone done either? Do I have to prime before i paint for good results? Well i'm going to test the strength of each using my skid plate

Half with primer and half with plastidip.

the surfaces were both preped, by cleaning with alcohol. I'm going to use 5 coats of plasti-dip and 3 coats of primer.

Well i haven't bedlined over it but i have peeled all the plastidip off of my ski plate and then repaint. What i did was took it off later it on cement and got a pressure washer and it just took all the plastidip off relatively quickly and then i replastidipped it. Don't know if this helps..

I would bed liner it, plasti dip isn't going to hold up to everything that gets scraped down there

I know, i'm going to bedline it, i'm testing bed liner sprayed over plasti-dip and bedliner sprayed over primer

I'm done using plasti-dip for most applications, i'm looking at spraying bedliner over the plasti-dip or spraying bedliner over primer..

You could pressure wash all the plastidip off then go with primer and bedliner.

Thats what i'm looking at doing, but if bedliner is just as good over plasti-dip and it can peel off if i need it to I would rather do that.

I doubt the bedliner-over-plastidip will work long-term. The problem (or benefit) with plasti-dip is that it doesn't have a 'permanent' grip on the underlying surface. Scratch it, and it will peel right off. If you paint over it, the paint is just sticking to the plasti-dip, not to the underlying surface.

This means, if you scratch the bedliner, it will likely go through that, the primer, and the plasti-dip and then it will start to peel off. Granted, the bedliner will likely be less resistant to scratches/tearing because it's thicker, but once it's scratched, it won't hold up any better than plasti-dip. On your skid plate, I don't think it will help at all...

I'm just using the skid plate as a dummy for my testing, and honestly i'm pretty scared to paint with something that is perminant. When i can easily over spray or mess up.

I've used the same bedliner on my outside trim (roof), roof rack, chrome door handles and even chrome wheels. I used plastidip on my mirrors and door handles, it came off my door handles in a week...I never use it on anything again.

Just clean well before spraying.
That stuff is tough and holds up to high pressure washer (3000lb pressure)

Just my opinion,

Ive used bedliner on my mirrors, doors, rims, and grill also. Works so nice, and if it chips you can touch it up real easy. The only thing that is still plasti-dipped is my emblems cause those would suck to tape off and I don't have the patience for that hahah

I would strip the bedliner. The bedliner will adhere to the plasti-dip and that stuff peels off so it'll all come off as a big layer.

 

[derian06]

So it sticks to trim and other surfaces with no primer?

It probably would as long as you clean it real good. Depends how much armor all has been used. It's always a good idea to take a scuff pad or steel wool to whatever your gonna paint. The duplicolor adhesion promoter is a real thin, clear primer.

I looked at lowes and couldn't find it, do you know a store that sells it?

It's an automotive product. Try AutoZone or advanced or O'Reillys..

The bed liner with plasti-dip under it was ALOT more protective, and peeled just as easy

This is with the primer, also really protective, and didnt chip.

Now I have to do just bedliner after scuffing it with steel wool and cleaning with alcohol[

Here is the clean pic i'll have the bedlined result tomorrow.

I vote bed liner, it is more heavy duty and it is an easy to re coat

 

[derian06]

Update: just bedliner did the best out of all three. No primer needed.

So straight on the metal, using just bed liner from a spray can is the best? Holds on great and no pealing.

 

[digglesworth]

Did you try it on any plastic?

From hitting it with a hammer and scratching it, it looks like it!

I'd follow the bedliner mfr's instructions. Any bare metal should get a real primer formulated to help the top coating bond. I don't think Plastidip is intended to be painted over. From my experience, I don't think I'd use PD anywhere that gets much traffic or abrasion. Once its film is broken, it just keeps peeling...and that's why its so popular.

Derian,Bedliner works well on plastic, chrome or anything you would want to coat, I sprayed the plastic roof trim on my H3.
