On my boat I was able to remove a painted on name just using acetone.

Marc-

Acetone can easily damage or soften gelcoat if left on for any significant period of time.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Re: Removing paint from Gelcoat

I just purchased new peel and stick name for my boat to replace the faded painted on one. The supplier, who does this proffessionaly, told me to use EZoff oven cleaner to remove the old name and nuetralize with white vinegar afterwards.
Any residual paint can be emoved with rubbing compound.

Re: Removing paint from Gelcoat

This is a 5+ year old thread. I suspect he got the paint off.

Re: Removing paint from Gelcoat

The Company that I purchased my new "Peel and Stick" name told me to use Easy-Off Oven Cleaner and nuetralize after with White Vinegar.
I hope it works as I plan to do it today.

Re: Removing paint from Gelcoat

Back in the day before decals, the professional sign (name) painters all used Easy Off Oven Cleaner. I do not know of anything better, cheaper or safer for the gel coat. Do make sure it is indeed painted on there, as it's very rare these days.

Re: Removing paint from Gelcoat

EZ-Off, the traditional product in a bottle NOT the new aerosol cans, was basically lye. Same as drain cleaner, but thickened to stick on vertical surfaces.

Lye is also sold as a paint and varnish stripper in paint stores, often is the active ingredient in purple industrial cleaners.

Yes, it usually works and works well, and since it is an alkali it will eventually soften or damage gelcoat and fiberglass if it is not thoroughly rinsed off, and followed by a mild acid (vinegar) to neutralize it.

But don't be surprised if there is a pale ghost left behind after you get the name paint off. Since that was shading and protecting the gelcoat beneath it, there's usually a brighter shadow left behind, and there's no simple way to remove that, although careful compounding and polishing of the hull may blend it in.
