plastercine v silkaflex 292
If...plastercine is an effective absorber of force and gave a positive result then I would hope that silkaflex could be an improvement...
Likewise with Isopon..
Assuming it's not a micky take..
The fibreglass is hard and the plastercine will harden and dry out. The silksflex is designed to remain elastic and absorb vibration in very demanding environments and subject to huge stress variations, without splitting, drying out.
Open to further suggestions before I get the drill out..
