Help with Burn mark on UPVC Window

[ricky9]

Hey there, I am having a bit of trouble with a burn mark left by an incense stick on my UPVC window.

Does anyone recommend how this burn mark should be handled? Some repairers have mentioned it cannot be repaired where as others say it can.

Can I repair this myself? or does anyone recommended anyone I can reach out to? (I am based in East London)

It looks quite deep, but could still be drastically improved, use wet & dry paper. You can buy wax kits for filling dents & gouges but I don't think they will help much in this situation.
