Default Peanut Butter Adhesive Release

Took the dreaded step today of removing the canopy after completing the fiberglass lay up. Wasnít sure what to expect but was pleasantly surprised by the canopy itself, BUT... I was shocked at the amount of adhesive residue left on the fuselage after removing the duct tape. Not sure if it was old tape, the amount of time since applying, cheap brand, or what, but I had a real mess on my hands. Started using Goo Gone adhesive remover but the going was very slow. I jokingly asked my wife if she wanted to help. She got a jar of smooth peanut butter and smeared it on a bad area for several minutes and... IT REMOVED THE ADHESIVE. It even loosened some epoxy that had dripped on the fuselage side sheets! Just thought Iíd pass this trick along.

In hind sight, it might have been better to have applied a layer of Mylar packaging tape first to protect the skins. Hopefully I wonít need to do this again but might be a consideration for those of you that havenít started your fiberglass work.

Moral of the story - donít be afraid to ask for help. Never know who can help.

Nice! You could probably get your dog to do most of the work removing it

Have used it for removing old masking tape adhesive. Interesting chemistry of peanut butter!

I layed down six layers of 6 mil plastic on top of the fuselage instead of tape. It was too many layers and the gap between the fuselage top and the bottom of the layup was too large. Just had to do some sanding on the bottom of the canopy where it meets the top of the fuselage. No tape, etc., required. Worked well and no worry about lifting off the completed fiberglass work. I'll do the same next time only use only two layers of plastic sheet.- easy.
Building finally

FYI - WD40 works well too on most adhesives i've tried.

Also, orange oil (sold as a bike parts cleaner at my local shop) works great on adhesives that acetone, alcohol won't touch. Also smells very good!
