    Pro Grade RTV

    I have Silicone Depot several times and have not been disappointed. I purchased the clear silicone this time and it is great. I like that the tubes do not have a seal that needs to be broken before use.

    Project 1 RTV Silicone rubber

    I used this in a mold for prospecting gear, a mat in my blue bowl, and it worked fine. A bit under 24hrs to fully cure.
