Potentially stupid question...

Like many others I'm sure, I'm looking to get a set of the plastic flatfenders Jerry posted up when I get some loot from Uncle Sam. I'd like to color match them to my Jeep, which is Moss Green. Since it is a Sahara color, my question is...did Jeep use special flexible paint for Sahara flares, and is it available? I've found plenty of color-matched paint online, but nothing specifcally(sp?) for plastic. I don't want to paint them and have it flake off the first time they take a hit. Or do you all think standard paint would be flexible enough?

Standard paint won't work, it won't adhere to the ABS plastic. Go to an automotive paint supply store where they should be able to provide you with a matching paint that is meant for plastics. Afterall, paint & body shops have to paint plastic bumpers all the time. I'm having some made up for mine to better match my Jeep's flame red color. It turns out the Krylon Fusion red I used is a bit too orange.

You might see if they can put it into a couple aerosol cans for you to make the job easier. That's what I plan to do when I order my paint which is what I did the last time I had them make up a batch of paint for me.

not a stupid question at all.... No there is not a certain type automotive paint specifically for plastics, there is however a flex additive you are supposed to put into your primer, paint, and clear coat, when applying to plastics.

There are diffrent steps to prepping, and painting plastics. You would want to prep your flares with a wet gray scotch brite pad, perferably with a bare plastic prep paste on the scoth brite pad. Then before you apply your primer you would want to apply an adhesion promoter, that is a pretty important step when painting bare plastic. Then yes you would want to add the proper amount of the flex additive to your sealer coat, color coat, and clear coat.

im not sure if automotive paint stores can put flex into spray cans as jerry suggested, it would be worth checking out if you were going to go the "buzz bomb" route. They do however make adhesion promoter in spray cans, I would highly recomend useing that before painting. Good luck

Well, back when I attended the Martin Senour Automotive Refinishing Class, the rule of thumb for automotive paint with flexible additive was "If the panel bends enough to break the paint, the panel will most likely need to be replaced". Flexible additive allows for slightly more flex than regular "cured" urethanes and enamels. I highly doubt you're gonna find a product that will flex to the point that these fenders are designed to flex and not crack the finish. While the fender is designed to take massive amounts of abuse, paint isn't.

Even the fusion paint I put on my factory flares (properly prepped) still popped when I flexed them too far.

To achieve a true "flexible" finish, the manufacturers would have to have the fenders molded in color.

Yep, that is true. Though if they get bent so far as to crack the paint it's likely the owner is going to be more happy they only flexed and weren't destroyed or permanently bent/dented as would happen with the OE steel fenders.

Good point about how much flex you expect out of these flares. I would be more concerned with prepping them properly and useing the adhesion promoter just so the paint adhears good, then as far as flex goes like he said if they are going to take serious abuse the paint will crack anyways.

I agree Jerry. These fenders are awesome!

I've always been a little disappointed with automotive finishes. Most industries have advanced through innovation. Sadly, the car paint companies have only advanced to keep up with EPA requirements. Of course, you can't really blame them because EPA requirements change everyday.

Not sure if it'd work with those flares, but there is a paint I used often for RC truck bodies that was SUPER flexible. It was painted on the inside of the body though. It wasn't really scratch proof, but held up pretty good.
Any hobby shop that sells RC race trucks should have it. It's brand name is Pactra...

I think paint has taken a giant step backward since they had to reformulate it to meet EPA requirements. Several iterations later I still don't think automotive paint is as good as it used to be before the EPA got involved.
