There's a series On BRITT TV about these boats,

Many thanks to all those who replied to my query about glue removal. I'm sorry that I haven't replied sooner but I greatly appreciate everyone's input. I use acetone for a lot of projects but hadn't thought to use it in this case. I'll let you know how I get on.

Yes, I agree with the other fellows—acetone does work, but it’s a very strong chemical.

In my case, I prefer using the Bob Smith Industries UN-CURE Super Glue Debonder. It’s much gentler and gives me better control when ungluing parts.

Just keep in mind, that acetone is a more dangerous chemical than its common use in nail varnish remover and general household uses implies. Nitrile gloves, goggles and plenty fresh air are very much recommended, especially if you are using it on a regular basis like in a model boat workshop. Check the web for more specific information!

I think that depending how big it all is you can put some gel nail varnish remover (gel type contains acetone) on a cotton pad. Wrap that and your fossil into a small parcel of foil leaving space for the fumes to circulate around the rock (foil helps keep the fumes in). Give it five minutes or so to soften and then try wiping the residue off with another lint free cloth that has nail varnish remover on it? Probably best if you don't let the impregnated cotton pad rest on the face of the fossil in case it doesn't all wipe off and to stop cotton wool sticking? You can get the remover at superdrug/Boots. Saw some gel nails removed this way which is what makes me think it would work. I use the stuff to get superglue off my fingers when building.

Acetone is the solvent I have in my kit. Works a treat to dissolve super glue. I presume it's the residue you want to remove rather than releasing the pieces and that could be tricky as the acetone evaporates very quickly.
Anyone else have thoughts on this.

Super glue can be removed using acetone, isopropyl alcohol, vinegar, oils, or mechanical methods, depending on the surface type.
General Guidelines
Super glue, or cyanoacrylate, bonds extremely quickly and strongly, making removal challenging. The method you choose depends on the surface material and whether the glue is fresh or dried. Always test any solvent on a hidden area first to avoid damage, and use protective gloves and ventilation when handling chemicals like acetone.

Hello everyone from a cold and windy UK,
My problem is not strictly about boats but could have a relevance. One of my hobbies is fossil collecting, I was repairing an ammonite (calcite, limestone, calcium carbonate) the other day with super glue and managed to squirt the glue allover the face of the fossil. My question is this.
What solvent dissolves super glue? Scraping it off is not a possibility.
I look forward to any replies.
Best wishes Tim
