Sika Primer 209D

I ordered the Sika Primer 209D on March 12th and it was shipped on the 13th. When it arrived I didn't notice that the ""Best Before' date was 1/2023. In fact, I didn't realize it until after I had installed my windows. Now I have two more windows and my 209D as well as my 206 G+P is expired. The question I don't have an answer for is what the impact to the qualify of my window installation is.

Worst company to work with on shipping. Called and ordered one small simple IMPORTANT item, the person taking my order on Oct 11 advised I would have this 4-5 days. Here we are Oct 20 and I still don't have it. Also ensured me the package was shipping UPS, then found out they transferred it to USPS, which totally explains why I don't have it and will most likely never see it. After speaking with others, it is clear this company does not deliver as promised most of the time and they apparently lie to customers? If you have an option to get your item somewhere else, I Highly suggest doing that!

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.

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.
