Decal Shadows

[sailsmanship]

Why is it that when I remove decals like a transom name or registration numbers, it always leaves a raised shadow in the fiberglass? Is it because UV rays deteroirate gelcoat and the area behind the decals do not? It is very noticable, and very raised to the touch. Could I block wet sand the area to level it out, or would that be too extreme?

thats the only way m8..sand and buff..

aye..half is a mystery..I believe due to polishings those areas are raised..but ive seen newer names removed with the same affected ghost and raised back .. dunno m8..

but yea..you have to sand and polish..
