How should they be treated? Should I clay those surfaces? Can/should they be waxed? I have done several searches, couldnt find the information I am looking for. Thanks in advance.
Some manufacturers provide a polish/wax for their product. I just use the same products I use on the uncovered surfaces: fine polish or cleaner plus a highly concentrated (50%) carnuba. It works fine. I'm sure that professional detailers such as Todd Cooperider, who occasionally visits these forums, will lend a professional opinion.
I was told by the guy that applied my clearbra not to use any petroleum-based wax products on the clearbra surface as it will eventually cloud the material. He suggested a product called Jetseal sold by chemicalguys.com. I have used it a couple of times so far and it seems to work OK. It's more of a 'liquid' wax that can be applied and then buffed off, and it's supposedly also safe on metallic surfaces. But it's only been a couple months, so can't really confirm any long term implications.
I have had clear bras on 2 of my past cars and my wife's car currently has one on it. I have used Zaino and Mequiars NXT with no issues, even their quick detailer products. I would not do a clay bar treatment on the clear bra material as it will scratch it. All other treatments should be fine as you would do to your normal car's surface. However, one tip I learned the hard way. Use painters tape to tape off the separation of clear bra to regular paint. This will prevent you from getting wax on that seam. Only alternative is if you have a really steady hand. Takes a lot of effort to get the wax out of there. Good luck! Deiger
Plexus has been proven to yellow film over time. It is meant for hard plastics not urethane. I have recommended to all my clients to use Zaino on their film... or other non petroleum based products. Of course yellowing will not show up on any other colors than white or silver... so if your car isnt either of those colors you are fine.
I have the clear bra on my car however I have water marks all over the clear bra and I have tried wax. I have tried all different kinds of spray shine, I have tried clay baring, I even tried compounding the clear bra (not with a buffer just with a microfiber cloth) and still to no avail the water spots are still there. Any suggestions anyone?
Unfortunately in this case as I have seen before you should replace it with the newest form of clear bra ie: XPel or the like. They actually have what is called Self Healing bras where they can take more abuse without distorting or stretching out of shape.
My installer gave me a can of Plexus. From 3M: After initial application of Scotchgard PPF, do NOT wash vehicle in a high-pressure car wash for 24 hours. After that time, wash and wax your vehicle as you normally would. Avoid spraying the edges of the film with a pressure washer or a hose to reduce the chance of lifting the edges of the film. For added protection, 3M recommends waxing the vehicle and film with 3M Performance Finish 39030 after installation to help maintain the gloss of the film. Wax build-up along the film edges may be removed with a 3M Perfect-It Detail Cloth, a soft brush or a Q-tip® Cotton Swab. Do not pressure wash your car for 24 hours. Never use pigmented waxes. Never use paste waxes.
This question can have various answers, as the answer depends completely on the type of clear bra installed. Some clear bras can be polished, and some can even be fixed with a heat gun to remove dull spots or water spots. If you let me know the exact type of clear bra you're dealing with, I can let you know proper maintenance. This is a clear bra on my old E92 M3. The clear left spot on the film is after being treated with a heat gun:
