hi

i am kind in process of learning and doing stuff. so not all the materials and all the equipment in the house
so i'am trying to improvise and find solution from existing materials and tools that i have.

i'am planing to do mould, but i dont have gelcoat.

so will thickened resin with fumed silica do the job instead of gelcoat.
i am talking about the mould for just a couple of uses.

thank you all for reply

i use epoxy
