3M 3000 UV is a one-part, moisture-curing elastomeric marine sealant with exceptional UV resistance.

I was interested in a black sealant for a built in cooler on my boat. 5200 would not have made sense as at some point it may need to be removed/replaced and there was no need for a permanent seal. I opted for this over 4000UV and made the wrong decision. The product was soft, flaked away easily and if touched at all with acetone, smeared and made a huge mess. I ended up scraping this away and redoing it with 4000UV, which I would highly recommend for a non-permanent use.

Sun resistant sealing sun roof for RV, stays pliable and can be removed if needed. Used in place of lesser quality elastomeric. Sealed up a couple of thru hull mounts on my sail boat as well. Stuff is awesome and can be removed. Used to cover over 3M 5200 as well with very good results.
