I contacted 3M about removing 5200. Thought it might help others too. Thank you for contacting 3M Marine and Specialty Vehicle Department. If the adhesive sealant is: UNCURED Clean surfaces with 3M General Purpose Adhesive Cleaner (part number #08984) or acetone. DO NOT use alcohol-containing solvents, which will inhibit the cure of the sealant. CURED Polyurethane adhesive sealant must be removed mechanically if cured. Use a knife, razor blade, piano wire, putty knife or sandpaper. Heating to remove 5200 and 4200 is not recommended because of the vapors given off and possible damage to the substrate. 5200 is meant for permanent applications. If removability is important in your application and you still need adhesive qualities use 3M Marine Adhesive Sealant Fast Cure 4200. Think of 4200 as being the same as 5200 but it is half the strength of 5200 and you would have removability. If you only require sealant qualities in your application, then use the 3M Marine Sealant Fast Cure 4000UV.

...but have YOU tried them?
Okay they are 'designed' to remove it...BUT has anyone put down the $$$ and TRIED them? Didereaux

yep
I've used one of them; but cannot remember which ... so I guess my opinion is of limited value. BTW: the one I used worked OK on cured 5200 (S/S to FRG).

interesting articles ...
Anyone interested in the chemistry of adhesives & bonding agents, should peruse the articles available from: www.specialchem4adhesives.com http://www.specialchem4adhesives.com/resources/articles/allarticles.aspx ie: Dear Gord, Rheology's Impact on Adhesives Processes Adhesives can vary in form, from thin liquids to pastes or solids, and their rheology plays a vital role in all of their adhesion processes. One important process is the adhesive resistance to internal and external stresses. This resistance is related to bond line thickness and, depending on the adhesive's form and rheology, this bond line thickness can be easy to maintain or not at all. This week's editorial tries to give some guidance on the parameters of bond line thickness. Take a look! http://www.specialchem4adhesives.com/home/editorial.aspx?id=1029&lr=ruas052&li=20380 Adhesion processes influenced by rheology also include application, surface flow and wetting, penetration into surface topology, diffusion over interfaces, and many others. Read today's article of the week by Ed Petrie, including a short introduction to the science of rheology and some examples, and understand the importance of rheological properties in day-to-day adhesive processes. http://www.specialchem4adhesives.com/resources/articles/article.aspx?id=1026&lr=ruas052&li=20380

always heat
I always heat 5200 to remove it. It hates heat and comes apart easily with it, even if it does produce fumes.

forget debond, try anti-bond
I've used both the debond 2000 and anti-bond 2015 recently. The debond had an awful reeky smell, damaged or stained everything around it, and was so awful to work with I gave up on it. The anti-bond is more civilized and will work if you do a lot of picking and scraping to help it work its way under the gobbier residue. Truthfully I find 5200 to be more trouble than it's worth. The parts on my 1984 Catalina 25 which had been sealed with ordinary marine silicone were still well bonded together and the silicone was still fresh and supple while the 5200 was all turning to powder from UV and sticking to the fiberglass but not the other critical materials. I use marine silicone for just about everything now, since critical parts normally have bolts and screws as well as adhesive to keep it all together.

We were the first!.....
to come up with something to clean up 5200- even fully cured and even off vinyl or cloth.Works on Sikaflex, silicone and uncured two part glues and resins. For years, I have used Island Girl Pink. If you have someting to big to remove, you can make slits in the sealant and allow the cleanser to soak. It will NOT damage underlying material like heat or solvents. To stop the reaction or to finish the clean up just use water. Being doping this at boat shows etc since 1995! There are even testimonials on this for removing from cloth upsholstery on a truck. BTW this is only one minor use of this product if you have it . Its here in the Chandlery of this site.

Rheology -
the science of deformation and flow of matter. The egghead answer - "Rheology - the study of the flow and deformation of matter, is an old discipline undergoing a renaissance. In its widest sense, it includes classical fluid mechanics and elasticity which treat the flow of Newtonian liquids, such as water, and small deformations of hard solids, such as wood and steel. The use of the special term "rheology" for these subjects alone would not be justified, since they have been extensively studied for more than 170 years, and are an accepted part of the curriculum in most universities. In practice, the word "rheology" normally refers to the flow and deformation of "non-classical" materials such as rubber, molten plastics, polymer solutions, slurries and pastes, electrorheological fluids, blood, muscle, composites, soils, and paints. These materials can exhibit varied and striking rheological properties that classical fluid mechanics and elasticity cannot describe. Though the word "rheology" was coined in 1929, the rapid development of the subject began 20 years later." Join the society at: http://www.rheology.org/sor/

Gasoline
Gasoline cuts cured 5200. This is why it is NOT recommended for fuel tanks. Use liberally but with caution. JC 2

what Patrick said ...
Thanks Patrich. The rheological properties of a liquid (like an adhesive/caulk) are dominant features that can be quantified to characterize its behavior, and the response of a liquid to a forced shearing flow is the basis for determining the specific rheological properties of a given liquid. General qualitative terms used to describe these properties are viscoelastic, Newtonian, non-Newtonian, thixotropic and dilatant. Quantitative parameters used are viscosity, elasticity, shear rate, shear strain, and shear stress.
