303® Aerospace Protectant™ on Plexiglass
303® Aerospace Protectant™ cleans up Plexiglass!
Plexiglass is a term used loosely to refer to several "hard" clear plastics used in lieu of glass, two of the most common being Lexan® and acrylic. You see this material every day. The enclosures at the bus stop; the windows on subway cars, buses, trains and aircraft; the windshields on race cars; the domed vent covers on the roof of a motor home or travel trailer; the clear panels that keep party-ers from falling out of the sky boxes at football stadiums and protect fans from 100 mph hockey pucks; a motorcycle's windshield, the visors on fireman and motorcycle helmets and a thousand other uses.
These are great plastics, but share some common downsides:
- They oxidize (fog, haze) over time due to UV exposure.
- They scratch fairly easily.
When visibility degrades to the point to where something must be done, the manufacturers recommend one thing: Replacement!
The thing to do is prevent the oxidation and minimize the scratching. The product that does just this, and wonderfully, is 303® Aerospace Protectant™. Start using 303® Aerospace Protectant™ when the material is new and reapply periodically:
- To protect against UV light and prevent oxidation.
- To repel smudging, dirt, and grime, extend the time between cleanings and make it clean up easier when cleaned.
- To reduce scratching by making the surface so super smooth that objects coming in contact with the 303®-treated surface that would normally dig in a scratch are often deflected instead.
Removing Scratches & Oxidation from "Plexiglass"
Clear plastics can be safely "buffed out" to remove scratches and restore visibility. A variable speed buffer, synthetic wool pads and cutting compound are all that is required. The two factors involved with doing it right:
- Light Pressure.
- Low RPM. 3M Super Duty cutting compound, available from most stores selling automotive paint, is recommended.
Follow these Steps:
- Wash surface to remove any built up dirt or sand.
- Squirt a little cutting / buffing compound on the wool pad, spread it on the surface area to be treated and with light sweeping motions polish the surface. Too strong a pressure or holding the buffer in one spot can burn and ruin the material. If doing a large area, periodically remove the cutting compound buildup from the pad with the "spur" made for this purpose, available from the cutting compound supplier.
- After cut-polishing, finish the job with 303® Aerospace Protectant™. On a large area, do a 3'x 3' area at a time. On the area to be polished, mist on a little 303®. With the buffer and a fresh wool pad, with the buffer on low rpm spread the 303® and then turn up the rpm (never more than 1800) and polish it in until dry, constantly moving the buffer in a sweeping motion. Again, too much pressure or holding the buffer in one spot can burn & ruin the material. The benefits of finishing with 303® A. Protectant are:
- Smaller and hairline scratches disappear and a like-new clarity is restored.
- Protection against UV caused oxidation.
- The treated surface repels dirt, smudges, stains, hard water spots, snow, ice, etc. The plastic stays cleaner longer and cleans up easier.
- Resists scratching.
For continuing UV protection, reapply 303® Aerospace Protectant™ every 2-3 months of exposure. Spray on, wipe dry, and polish to a high gloss.
Clean surface. Spray on 303® Aerospace Protectant™. Wipe completely dry with a clean, dry, absorbent, non-abrasive cloth. Then with a fresh cloth, buff to a high gloss.
