Extremely satisfied!
Works great! I bought this glue to fix the windows on my boat, and it worked perfectly. It’s strong, easy to apply, and dries clear, which made the job look clean and professional. Even after being exposed to water and sun, it’s holding up really well. I’m very happy with the results and would definitely buy it again for future repairs. Highly recommend it for anyone needing a reliable, waterproof adhesive!

Great product for mariners.
Thicker than toothpaste, seals great. No sagging or dripping.

Great product, but missing nozzle makes it unusable
I love this product, can't be beat, but it came without a nozzle, so it is useless

missing item
The product is good, but why is it being shipped without the applicator? Happened 2 out of 3 orders.

Worked well in my application. Set up and cure time was reasonable.

Worked good
Used this marine sealer on a repair to my pickup bed rail. Easy to work with and blended perfectly. Be warned this stuff takes days to cure out. Will have to wait and see on longevity but, the stuff sticks very well to metal and even plastic. Expensive, but worth it.

I'm a big fan of Sika products in general, and having repaired a convertible rear glass with a very similar sika product in the past (which is not available at the moment), I decided to go with this one for a similar repair on a different car. Turned out great, this adheres very strongly once cured (go for the full 24hrs or even more if you can) and the seal is now completely leak-free. The added "uv resistance" is certainly a nice feature. Do bear in mind that this stuff is extremely messy to work with, and will stain anything it touches (including fingers) so proper preparation, protection and care when applying are most recommended. That said, once cured, it's fairly easy to scrape any over-application off the glass with a razor blade (DO NOT try to remove/cleanup any of it if it's not completely cured, you'll end up with a huge mess... Ask me how I know! ). There's very little smell/off-gassing/VOCs, so working in an enclosed area is not an issue. OH, as other reviewers mentioned, the little plastic applicator tip was missing, which is a bit of a bummer but not catastrophic by any means as any tip from standard silicone or caulking tube will do. This tube does fit any standard caulking gun, and I don't see how you could apply it without one.

We just purchased two of the Silkaflex-295. My husband loves this product. He said it's easy to work with and worth every penny. Just as I was going to write this review I noticed that many reviews mentioned that their delivery was missing the plastic applicator. Well we received one with and one without. I'm not sure why this is happening but they were very quick at sending a replacement. Hopefully this issue will soon be resolved for future orders.

The front glass of my boat had recently gotten loose and threatened to come off completely. This adhesive is resistance to outside elements which is what convinced me to give it a try. The results are fantastic! If you own a boat and need to fix something on it, this Sika product is top notch.

The caulking tube is designed more like a grease tube than a caulking tube. Should have been tough as nails, but nope! The bottom sliding plunger that pushes on the inside of the tube failed, went sideways, came out all over the caulking gun, had to throw the caulking gun away, finished the job with nitrile gloves after cutting the tube apart with metal cutters. Not impressed. Maybe it's a one off failure? Not sure. Usually Sika makes much better products.
