Eastwood Flexible Strip Caulk Bk 2-lbs is rated 5.0 out of 5 by 11.
Rated 5 out of 5 by from Better than 3M strip caulk I've used the industry standard 3M strip caulk for decades. But in recent years when I ordered it, each time the product has been smashed into the package and hard to use. This wasn't a localized incident and it wasn't careless shipping. 3M just mashes it into the package. So, this time I changed gears and ordered the Eastwood version of strip caulk. Much, much better. It's properly boxed and works very well. After ordering this, I won't ever again use the 3M stuff that most places sell. Eastwood really sells a good product here. My highest recommendation.

Rated 5 out of 5 by from Great stuff! This caulk is just what I needed for my old 1949 Willys Jeep. The original stuff was pretty nasty after 65 years! The caulk is easy to work with and there was PLENTY in the package to do several cars. Great stuff!

Rated 5 out of 5 by from No Substitute When you need caulk like this, nothing else will do. The black blends in with lots of stuff underhood (and behind windshield rubber). Strips are easy to separate in the package and easy to use!

Is this for exterior use. How do hot & cold temps. affect it?

Asked by: whatever
This product can be used in exterior applications, as it remains flexible and doesn't dry out. This type of product was commonly used in engine bays, and was not affected by the elevated temperature.
