Excellent from Derek Rayner on 09/05/2021
Used as a joint in place of a thin rubber seal on my steam roller water tank. A much easier method of making a joint in this instance since it does not distort and squeeze out like a rubber joint which then looks 'messy' and the excess mastic can easily be cleaned up with white spirit. I'm very well pleased with it.
I believe it is very good and should do the job of resealing my boat windows from Tony Shea on 09/12/2020
