how do you remove old boat lettering

[dvuyxx]

Was the lettering painted/sprayed on with Awlgrip as well? If it was a "lesser" paint, maybe it can be buffed out and then a rubdown with light buff with awlcare? First, if it is a paint that isn't as tough as awlgrip, it might be pulled off by rubbing hard with MEK.

I'd be careful with MEK. It can get under most finishes. Not sure about Awlgrip? Even if it doesn't look like it right away later it might peel?

neverknow, point taken ... I would keep the MEK right on the lettering and do small areas at a time. You can also backwipe with a wet rag to dillute the MEK after rubbing. With awlgrip underneath, your options are limited for removing an overlay of paint.

Found this from Awlgrip.
AWLGRIP ONLY: Solvents such as AWL-PREP -T0008, AWL-PREP PLUS-T0115, AWL-PREP 400-T0170, toluene, lacquer thinner, M.E.K., acetone, or kerosene may be used to soften or remove heavy build ups of grease and grime, felt tip markings, or aerosol spray paint on the AWLGRIP Topcoat

But to your point, proceed slowly testing in a small area first.

If it's not paint there's a product called marine formula by debond corp; I use it on all adhesive, including 5200.

It will not harm gelcoats
