The manufacturer has a good write up on how to use this product. It worked as advertised with no leaks now for 4 years. My only complaint is that the 1 part primer is expensive and has a short shelf life, so you use what you need and throw the rest away. In my case, the two Bomar hatches I fixed used about 5% of the primer so most of it was discarded.

Great stuff however it has a shelf life and the volumn is all or nothing.... Too much for small jobs yet necessary for the installation process.

I purchased this 209 Primer and it was shipped to me on 5/16/17, it expires at the end of July. It is close to $90 a bottle and I used very little of it. How about Sika providing smaller amounts, or Jamestown and other distributors prorating the price depending on shelf life? It has a 9 month shelf life, but, I was down to 2.5 months when I got it.

Product seemed fine but as with the activator, there was WAY too much. I had two windows to do on my boat. I think the can I paid over $50 for could have done a couple hundred at least. Plus, the same cost and amount of overrun on the activator made this almost a $200 project to rebed two deadlight windows on a sailboat. Ridiculous. Plus, one of them came with a "best used by date" that was only 45 days away. Kind of makes a tube of silicone look a lot better.
