What do you use to clean it? I have read on multiple sites that people use the 303 protectant. I tried this but it doesn’t seem to remove the bug stains that are set in. Before I try harsh chemicals I hope to hear someone has a safer option. I guess I either attempt to clean it and screw it up or just have it removed.

Maintenance and Care-polyurethane protection film is porous, that's why it's so important to keep the film sealed. Dirt, dust, and other air born impurities left on unsealed film will eventually cause the film to become dull. Clean and maintain its surface with ( Z-8™ Grand Finale Spray Seal) or a plastic cleaner (Plexus®

Plastic Cleaner, Protectant and Polish) tape the edges of the auto mask and lightly glaze over the material; start at the centre and work outwards, do not use detailer’s clay as it will cause micro-fine surface scratches.
Ultra Violet Protection; more correctly, UV absorbent is a sacrificial ingredient that needs to be re-applied on a regular 2 – 4 month basis (dependant upon climatic conditions) - 303™ Aerospace Protectant

1. To clean stains - use a d-limonene based (citrus) 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’. Use Z-14 Plastic Magic Cleaner & Polish™ orPlexus® Plastic Cleaner, Protectant and Polish for maintenance and to remove any finger marks / smudges (avoid the use of abrasives)

2. To remove minor scratches in the film - (tape the edges of the auto mask when polishing the vehicles paint, use a high speed buffer (white foam pad only) and lightly glaze over the material. Menzerna Final Polish 106FF, LC White foam pad at 800-900 RPM do not use any downward pressure and maintain a fast linear speed than used on a paint surface; if you apply too much heat to this material it tends to ‘lift’. It is also 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 (See also 3M website- http://www.mmm.com (http://www.mmm.com/))

3. What can be done about wax build up along the seams and how can I avoid it?
Wax will leave a white line on the seam, it is recommended not to wax over the seams and wax the film and uncovered portions separately to keep from wax build-up. If you accidentally wax over the seam, soak a Q-tip / swab in a 1:1 solution of isopropyl alcohol (IPA) /distilled water; gently wipe the seam, once the wax has dissolved use a micro fibre towel to wipe the residue from the edge of the clear bra.

4. Clear bra polish- Menzerna PO 85 RD3.01 LC Blue foam pad 1000 RPM do not use any downward machine pressure and maintain a fast linear motion

6 Polyurethane protection film is porous, that's why it's so important to keep the film sealed. Dirt, dust, and other air born impurities left on unsealed film will eventually cause the film to become dull
To remove ‘clouding’ - from the paint under the clear bra; the suns heat, a heat gun or a hairdryer will remove it.

That is exactly what I was looking for. Thank you!! I only wish I had known to seal the bra when it was new.
