This may be used on other frames but I can't guarantee the results. I have a pair of Racing Jackets but they came with a matte frame and gloss jaws. I've always hated the gloss bits and finding aftermarket jaws is a nightmare. Getting them shipped to uk is even worse so I looked at how I could mod them. First thoughts was to go for a total gloss so I polished the whole frame using very fine motor cutting polish with a microfibre cloth. This gave an over all gloss result which whilst nice but really wasn't the result I wanted. How to turn the whole lot matte again was now the challenge. After much googling the common solution to turn gloss plastic matte is to use a scotch brite pad normally found on the back of kitchen sponges. If you want professional results then you're looking a blasting techniques which can be expensive and destructive. So sponge in hand I did a quick trial on the back of one arm and this indicated that whilst it removed the gloss it left quite a rough finish with lines or swirls, not ideal. This got me thinking about different abrasives and application techniques. Whilst getting ready for work the solution was in front of me. I have an electric rotary toothbrush with a replaceable brush. This would be a good applicator I just needed the right compound. Whitening toothpaste did work and left a nice minty smell, but a trip to the store found a fine abrasive paste used for polishing metal. 10 mins work and the end result is a clean matte finish with no swirls or lines..
