This worked really well to seal up the seams in a pair of rain pants that I made.

Thanks Amy! We would love to see your rain pants if you are willing to share it with us on Instagram! Let us know if we can do anything else for you in the future.

Works well as a seam sealer

Have used this for a couple of projects and it has worked out well 😊

We love to hear that! Thanks for leaving us a review George!

messy but works great!!

Very new to MYOG so I started out with silpoly and the silicone seam sealer to make a roll top dry bag. Made french seams and a square bottom bag, sealed all the seams inside and it is completely waterproof!! I'd use gloves to apply instead of the applicator. Overnight and it's dry. Inexpensive way to go for waterproof bags.

Sounds like you are off to a great start as a new MYOGer! If you ever have any questions about making or future projects, we're always here to help!

Exactly what I was looking for. Fast/accurate shipping. Will buy from again.

Thank you so much Reid! We're glad you found what you are looking for!

Silicone sealant

Easy to use, and worked great for some small dry bags and resealing some older ones.

Awesome! We're glad you were able to seam + re-seam seal some bags for added life. Let us know if you have any questions about future projects, we're here to help!
