Butt plates

[ROGERIO OLIVEIRA DA CUNHA]

Hello Barrie. I thanks your information about butt plates. I would like to
do an experience with the option 2 but I need more information about PLASTIC
PADDIN in order to find here in Brasil something like it. We have a product
called PLASTIC and it is a plastic dough or paste that you mixture it with a
catalyzer and in few minutes it becomes a very hard material and you may use
it to repair plastics, woods, cars, etc because it have a great adherence.
Another product is ARALDITE and it is two doughs in different colors and you
mixture the two in order to obtain a product that in 2 hours is hard. Can
you help me? Thanks.
