Correct product to remove yellow veil on lighthouses

This kit quality is quite good, but the price seems a bit high because it contains no sandpaper, only polishing paste and a product of glossing over the plate and felt and a (large) microfiber cloth.
Packaging is very correct.
In use with a drill battery (1400 rev / min), polishing paste is effective in removing the yellowish film on my phres Clio2: 5 minutes on one side is sufficient for my most recent lighthouse to pay him proper transparency.
On the other side, the lighthouse is older, it took more time but the yellow hand sailing well.
This kit does not erase scratches, for there is no risk against too attack the glass. He returned in any case much less than to polish the headlight by a pro (last time: 80 for 2 lights, life: 2 years).
