You can look up the 3M 4200 and 5200, there's tons of info from 3M and others. They are both called "adhesive sealant" by the manufacturer, meaning they adhere things together as well as seal them. I have heard 4200 called more of a sealant and not so hard to remove while the 5200 is definitely adhesive as well as sealant and very hard to get off of anything it gets on. So the 4200 is more "removable" - that being a relative term! cheers, John S. On 09/17/2013 08:26 PM, Sandy wrote:

Hi All -
I will be re-bedding my teak handrails ect. I have been reading about various marine sealants. According to Don Casey's book, he suggests using a Polysulfide if you ever want to get the item off again. Which I may need to do someday.
I know many of you use the 3M 5200 product which is a polyurethane. And according to the Don Casey book is extremely difficult to remove if you ever need to. In researching the sealants, 3M makes a 4200 that is supposed to be easier to get off if the someday comes. Has anyone used it?
I hope you can let me know your experiences & recommendations.
Am I over-thinking this?
Thanks!
Todd
