Used this product on mine http://www.invisionsales.com/lightin...t-maintenance/ and it worked well. Guy27 is familiar with the product and the results on my car.
I am not 100% happy with the results after roughly 6months applied ( sealer abit patchy ). The tricky bit is the final sealer coat application. Its drys very quickly but doesnt harden for 24-48hours. Comes down to how steady quick and precise you are appling the sealer I started top to bottom right to left with a 2pass only rule ( Had to start again on 1 side lens Not happy) A google search will find lots of photos and home users finished products.
