Thank you for making me go back and look at the ingredience of these two products.
They make Life Caulk and Life Seal. I have used both. The Life Seal did as advertized. The Life caulk did not.
Why it did not, I do not know. Let me just say that after a few months it leaked. Later when evaluating the leak, I saw that I had used Life Caulk rather than the previous product Life Seal. The packaging is too similar on the products and I was not aware of the differences.
I was working on a project and needed more sealant and quickly grabbed the caulk off the shelf instead of the sealant. I wrote the company about the packaging and they never responded.
In summary, the Life Seal did as advertized. The Life Caulk did not. I do not know reasons. The usage in both was above waterline as surface sealant/adhesive on old fiberglass boats.
I am still replacing the the Life Caulk. At least it is easily replaced compared to 5200. My comments are based on my experiences only and in each case may be do to working on old sailboats and due to
idiosyncrasy of that boat.
See their web site for accurate discription of uses and products:

However, the Life Seal is a 'marine silicone and polyurethane' whereas the caulk is a 'flexible marine polysulfide sealant'.
I would use the Life Seal again, but not the caulk. At least until someone shows me that it works on another boat. Who knows, maybe it was just an old tube? I guess I will have to look at expiration dates now.
