I have clear bra over a white car and after a year, I have slowly noticed the yellowing of the film (ventureshield) and some stains from bugs and bird droppings. I've maintained the film with Plexus after each wash but it doesn't seem to remove any of the stains and I'm begining to notice the yellow.

Is there any way to remove the stains? What about the yellowing? I've read that the film can be polished mildly with a PC (but some disagree). Would this help with the yellowing? I know on a white car it cannot be avoided 100%, but could anything be done/used to restore it a little or lessen it?

Thank!

 

Maintenance and Care
1. To clean stains use a citrus based cleaner (P12S Total Auto Wash) polish the paint and the clear plastics separately, tape the edges with masking tape. It has a clear coat so it can be cared for like a clear coated paint; use Zaino or Klasse as they will dry ‘clear’.
2. Use Z-14 Plastic Magic Cleaner & Polish™ or Plexus® Plastic Cleaner, Protectant and Polish for maintenance and to remove any finger marks / smudges
3. To clean and maintain the surface any product used on a clear bra should be optically clear and provide UV protection (Z8 Grand Finale Spray Seal or Optimum Opti-Seal)
4. Product application - start at the centre and work outwards, do not use an abrasive compound on the plastic surface or detailer’s clay as it will cause micro-fine surface scratches.
5. Another caution is to avoid buffing over the seams, which creates a noticeable wax line as well.
6. To remove ‘clouding’ from the paint under the clear bra; the suns heat or a hairdryer will remove it.
7. Providing protection from ultra violet radiation (UVR) is very important to avoid photo synthesis (colour fading / yellowing) UVR protection is a sacrificial / renewable component; this is due to the UV protection layer being degraded by exposure to the elements (sun, sand, road or sea salt, and etc) so it is imperative that you renew it and needs to be re-applied on a regular 45 to 60 day basis (dependent upon location and environmental conditions) Application- use 303™ Space Protectant, spray product onto a micro fibre towel, gently wipe surface working from the centre outwards
8. To remove minor scratches in the film (tape the edges of the auto mask when polishing the vehicles paint) Use Menzerna Final Finish Polish / Super Finish (PO106FA) and a (POC) Black Finishing foam pad 1000 RPM / speed # 4-5,do not use any downward machine pressure and maintain a fast linear motion. It is important not to apply a lot of pressure to the film as this may lead to burning of the surface. Use a Q-tip and some isopropyl alcohol to clean out the edge
Alternative -Novus Plastic Scratch Remover with a LC White pad using a PC speed # 4.
9. What can be done about wax build up along the seams and how can I avoid it? Are you sure it's wax and not the glue from the Clear Bra? As it gets warm, some of them will shrink a little and leave residue around the edges. Gently remove with an adhesive remover on a micro fibre towel. Be sure to go over any paint that you get the adhesive remover on with a protective wax; put a vinyl protection on any clear bra you get the adhesive remover on.
10. When waxing around a clear bra, mask off the line just a little over the edge with blue painter's tape. Wax will leave a white line on the seam, use painter’s tape to mask the seams before polishing / waxing and wax the film and uncovered portions separately to keep from wax build-up.
11. When you remove the tape just wipe off the wax on the paint. If you accidentally wax over the seam, use isopropyl alcohol (IPA) and a Q-Tip or a damp micro fibre towel and rub it off.
Maintenance / Care -Zaino Z-CS Clear Seal - wipe on, and wipe off (WOWO) walk away, no buffing, just allow to air dry. Use on paint, glass, wheels, plastic, clear bra, or trim for the protection, durability, slickness, and gloss that Zaino is most renowned for. All surfaces are protected against potentially damaging exposure to sun or ultra-violet light with UV inhibitors.

IMHO, Plexus is something to highly avoid...just take a look at the nozzle after some time. The white portion actually turns yellow. The film will yellow on its own after 6-8 months depending on care. I advice using a simple paint cleanser to polish, I use Swissvax Cleaner Fluid and you can use a high quality detail spray to protect...something like swissvax Nano Express or quick finish.

 

Sean, there is butane in Plexus, which dries out the pores of the film. We realized this some 2 yrs ago and completely discontinued its use. We also have our own product line specifically designed for the care of the clear coat on 3M, Venture, Clearshield and Xpel's film. http://www.premiermobilegroup.com/pf1_products.shtml

We will also be releasing our PF1 TTR line that is designed to remove staining. Especially with tar and rubber that can scuff the film on the track and leave black marks. The product is available currently and will be officially launched in one week.

 

PF1 Film Cleanse & PF1 Crystalline, products made especially for transparent film, interesting...

 

thats for the info! can i polish the clear bra with a PC to clear up the film and remove the yellowing?

 

Before deciding on performing anything that may damage your film, we recommend you first have your installer take a look at the film. Let him decide what needs to be done.
