Chuck C.
5.0 out of 5 stars Outstanding adhesion for a silicon RTV. NOT thin
Reviewed in the United States on March 2, 2023
Verified Purchase
This product adheres very well compared to other silicon RTVs I've used, especially when applied to roughened plexiglass. One commenter claimed product is too thin, and I was glad to read that. But, actually, I found product is quite viscous, as most RTVs are, and I would prefer it to be somewhat thinner. Considerable effort is required to squeeze product out of the tube and product does not flow across surface it is applied to. For superior adhesion to plastic, in comparison to other RTVs, I give this product an A+.

4.0 out of 5 stars Stiffer than expected
Reviewed in the United States on June 4, 2023
Verified Purchase
This was stiffer than I expected it to be. Letting the tube sit in hot water for a while helped, but, unfortunately, because space was extremely limited and I bailed after using it after only about a foot. I found it impossible to get my hand into the space to squeeze the tube tightly enough to really get enough silicon forced into the crack. Not entirely the products fault — I’ll find a use for this with no reservation — but I feel that the force necessary to squeeze the tube was worth mentioning.

5.0 out of 5 stars Must Have For Any Auto Enthusiast
Reviewed in the United States on September 21, 2020
Verified Purchase
I used this mainly to assist in anchoring a new carbon fiber spoiler to a 2016 CTSV. The description for this product was spot on!! Easy to use & cleanup as well! Tack time & final setup of 24 hours was great. If I had a negative, it would be that it should be offered in a large tube so a large application gun could used to apply this product in a smoother fashion. The smaller tube & applicator causes you to stop & start multiple times to finish the job. Great product!!!
