From the "Know-how" section of this month's (June's) SAIL magazine: A guy reports success breaking free old deck fittings bedded in 5200 using a guitar string as a flexible saw. Sounds like another reasonable approach to dealing with this often-occuring problem...damn, that stuff is bombproof.

Tuco,
You just may have solved my issue. I am trying to remove the boards glued to the hull with 5200. I was having a MacGyver moment the other day trying to figure out a "saw" that I could use to get between the boards and the hull without too much damage to the hull. The putty knife just isn't working for me.

"He came up with the idea of using an old string from his guitar to cut through the joint between fitting and deck. With the wire pulled tight between his hands, he was able to saw back and forth through the joint and little by little break the tenacious bond [!!] without damaging the deck."
The writer adds the following obvious point: "...twisting the ends of the wire around a piece of wood and wearing a thick pair of gloves makes the job easier on your hands."
Good luck, Kamie. I was stumped for days by some 5200 that I was trying to get out of a one inch hole through my transom...razor blades didn't work, nor did drill bits, super sharp small chisels, chemicals, an exocism by our local priest...please keep us informed.

I have heard of guys using heavy gauge monofilament or dacron line for this same purpose.

I used a hacksaw blade to remove some under my console. they make those camping saws that are like a wire with two rings on each end to hold. That does the trick.. and easier to hold onto than guitar strings.
You wanna see some guitar strings come and see my bluegrass duo at North Light Books in Cotati tonight... we'll show you the proper use of guitar strings endorsed by the Memphis Jug Band!

Tony, this sounds quite similar to the piano wire trick the Good Fellas on Federal Hill in Providence RI used to employ.
It too selectively removed the upper part from the lower if used correctly.

I cut wheels of cheese using leader material.
The 5200 finally gave way on my teak trim steps after 15 years of sitting in the sun and weather.
If the 5200 is laid on thick you might have better success with bass strings that are double wound, otherwise the single strand guitar strings should work. You might try some monel trolling wire if you fish that way.

Yeah, I've seen that trick used to remove broken windshields, by cutting thu the sealer around the perimeter, You just work one end to the wire under the glass at a corner, and back out on the otehr side of the corner. Then you wrap both ends around some big dowels, and saw away, pulling towards you. Cuts like butter.

You can buy a cable type "Survival Saw" that had bits of sharp carbide bonded to the wire. Might be quicker than a guitar string and more comfortable as they have rod handles on each end. BillS

I'd try the smooth wire first before going at it with one of those survival type saws; that thing will cut whatever it comes in contact with, including your hull. Piano wire would work well too.

Guys, best to go to your local marine store and pick up the 5200 sofener and let it soak in. It does work. Anti-Bond 2015. Doesn't harm the gelcoat either. Good luck and remember if you can EVER see yourself wanting to remove something in the future don't use 5200. 4200 or the like is fine for bedding just about anything. Take care,T

get one of those heated wire tools they use to take out windshields
kamie posted 06-09-2006 09:03 PM ET (US)
I will probably try a combination of the Anti-Bond 2015 and the guitar strings. I rejected the saw idea since I want to salvage the gelcoat.

I read there is a product call "Criptonite" that will dissolve 5200. I am not sure of the spelling.
