Mending burn holes in laptops?

How can I mend a burn hole in the laptop next to the keyboard so that you can't see anything anymore? Make plastic hot?

Sticker on it or exchange housing.

Fiberglass filler.

Heating plastic is first of all a plausible idea, but afterwards it can happen that, although your hole is no longer recognizable, but neither feel let alone a laptop case.

if the lappi works, stick a sticker over it, ready. Or buy the appropriate housing part as a replacement.
