Default Can you paint over Line-X?

Looking for some info on what my best options are.

I recently had my rockers linexed black on my blue granite truck. I was originally told that painting over the black linex with original blue granite wouldn't be a problem and a better option as color matched line x would fade. Now I'm being told that paint won't stick to the linex...

Anybody have any experience with this? I don't really want a black truck to match my linex, definitely don't want two tone. I want a color matched truck and any options that may be available I'm all ears.

It tends to crack and peel off over time as the line x is flexible, a good primer and a very thin layer of enamel may hold up for a while and be cheaper to fix if it doesn’t

Good bed liners are typically polyaspartic which is notorious for its resistance to recoating. Pealing and delamination is a big possibility.

With that being said, I worked with a manufacturer a few years ago on a method for successfully recoating.

You will need to abrade the surface so there is zero contamination and that the whole surface is covered in fine scratches. Then prime it with an acrilic primer. The primer is very important. It needs to be a high quality, pigment free and very low viscosity like water. then within the recoating window of the primer apply your coating of choice.

As mentioned by WVRigrat05 the choice of paint or other coating will be important due to the semiflexable nature of the line-x to prevent chiping. I would paint it with another simi-ridged coating. Something that will not get super hard

OK, this is completely off the wall, but couldnt a person make that plasti-dip stuff work for this application?

I was under the assumption that bedliner/linex could be tinted before application? If thats is true, then why wasnt that done initially?

plasti-dip would work but only for a short time. plasti-dip doesn't like to stick to anything for very long

If applied correctly it will last years. I have 5 years on my grille now and that's in AZ summers.

Now down on rockers is a different story because of debris from the tires.

Yeah, no doubt right. That's what I Would have had the line-x told me that in the first place. He said I'd be able to paint over no problem...

I'm looking for solutions at this point.

Thanks for the info man! I'm almost regretting the line-x at this point... if I had the Propper info to begin with it'd be s different story.

Iíve always used raptor liner, Iíve done a few complete trucks with this product and they have tintable bottles. You can choose any color you want and mix it, add high gloss or flat. This is the best stuff Iíve seen/used. Best to mix the paint with the product vs having to paint over it.

How about using Krylon Fusion? It is formulated for flexible materials like plastic.

I have not painted over one yet, but if the need arouse I would not hesitate.

1. Clean it very well, Dawn dish soap.
2. Scrub with a red scotch brite pad.
3. Apply Bulldog adhesion promoter.
4. Apply quality 2k urethane primer.
5. Apply base coat.
6. Apply clear coat.

Yes Line-x is flexible, but so are many other parts on your truck. Think bumper cover here, look at all the cars and trucks out there running around with basically plastic bumper cover. Those are painted base coat clear coat all day long. Use urethane.

Here are a couple pictures of the bumper cover I fixed on mom's 2017 Equinox. Trust me, that bumper cover is more flexible than Line X.

I just donít see how after you paint the bedliner the first thing you throw in there is going to scratch the paint off the soft plastic.
