I have just finished with a drift race car complete redo.
It obviously had HUGE stickers on of the sponsors.
I used thinners with "Domestos" (Think it is a drain/strong kitchen cleaner) to keep the thinners from evaporating very fast.
I used this mix with red scotch bright.
It worked well but it was really a insane experience.
The stickers was on the car for around a year plus.
Covering 50% +- of the whole car, so it was a lot of "tungsten carbide" glue!!
How will you remove it???
PS. P60 on a strong DA almost does nothing.
