I'm thinking the heat gun had stained the adhesive into the gelcoat.I removed them with a heat gun, removed all of the residue, even sanded the spots with 400 then 600 grit paper and followed it with rubbing compound, polish and wax - but the shadow of the numbers remains. It's almost a faint light tan color burned into the gel coat.
LOL. It does look like it's hiding doesn't it? 1968 912 to be exact.I'd give the bleach a try. May do it with little to no effort. (Looks like a sweet, vintage 911 is hiding behind your 'fish.)

Being in the boat business for 30 yrs, plan on living with it. UV and sticker glue have done their job over the years. You can sand more, but its possible you'll go thru the gel before the shadow is completely gone...not to mention getting a larger area of slightly different color. Matching gel on my 69 fish is fun.
Boat name instead of reg numbers??
Also, there is a Native American idea that only the Great Spirit can make something perfect, so a purposeful flaw must be left in the art, and that is where the Great Spirit will enter as well.
