20201116_121450.jpg I have tried everything , strong stuff to. it will not remove anything. What is that hard stuff ?

[s0_big]

Have you tried to polish it away? Otherwise use some heavy duty polish if you already tried "strong stuff"

[Bowie69]

Maybe acetone?
or is it dried out wax?

Boiling water/tar remover. Looks like sticker residue so those two together should work.

Use steam.

Glue and tar remover should do it

[S2_avant 19930325]

Do you have a brand on that for example ?
I tried tar remover. No help. Tried the rhing that tästinks that you use to clean brushes after painting car. Yried aceton. Nothing. It is VERY HARD. Troed to schratch it of with plastic knife.

You could try "live with it"! it works very well for me.

haha ,, tried that to

Is it actually something stuck on top of the paint or is it the paint / lacquer itself?

[S2_avant 19930325]

Something is stuck on the paint

Factory anti-corrosion wax. Good luck

Heat gun or steam

Still got a 15year old tin of Autosmart Tardis that took most things off any part of the engine bay; xylene based like most others but
always worked for me
