Depending on the finish, I've also had really good luck with engine de-greaser. I had a piece of wood that was filthy with age, grease and grime, etc. -- non-boat project that I doused with engine de-greaser on a whim. It removed all of the grime, etc as well as the finish. Which was great for me. The original finish was most likely tongue oil and varnish.

A multi oscillating tool with a straight blade attachment may help. It was super helpful when I removed a deck mounted skylight on my boat. The triangular sanding attachment was also helpful after removing the bulk area of old sealant with the blade.. No doubt, saved hours of hand scraping & sanding.

If DeBond can remove 3M 5200, it can remove ANYTHING. :thumbup:
My bigger question is can you re-bond wood that has been de-bonded with DeBond or does the oil left behind in the wood make it hard to get a new bond. Has anyone tried it?

I have mineral spirits so might try that first. Just curious, if you get the debond on wood, does it dry out enough that you can reseal it? I have some teak trim that some pieces have broken off and some are still sealed hard. Would love to get the remaining pieces off to varnish and put them back on.
I cannot answer that. I have never removed teak from a boat. The only thing I've used Debond on is winches, hatches and deck hardware to clean and either rebed or install new winched. Regarding trying mineral spirits first, the mineral spirits are used to remove butyl off of hardware before remounting with Marine Grade Bedit Butyl tape. The Debond is to remove items that have been mounted with 3M 5200 and other similar products.

Finally warm enough to finish the window job this weekend. Adhesive needs 60+ degrees.
I did not try debond, b/c I never ordered it, but acetone wins over mineral spirits to clean the old adhesive off. Acetone and a lot of rubbing and thumbnail scraping. But it eventually comes clean. See pics.
I installed the 2 on the side that was leaking this weekend. The difference is amazing. I included pics to show the difference b/w the old crazed plexi and the new.
Did not need to reinstall screws. VHB tape is all that is needed for the next 30
I had to buy full sheets of plexiglass to get my 4 windows so I went ahead and had them cut extra windows sets. If you are in the Chesapeake area and would be interested in a set and help me offset my cost, dm me. Hate to see them just sit in my basement.
