Putty Help

I know i'm supposed to use Tamiya Epoxy Putty, but there are 2 kinds. Smooth type and Quick type. I want to use it to build onto resin. What kind would be better and will the putty stick to the resin if i rough it up a little? Thanks.

i think it should stick to the resin (not sure, never tried). Get smooth type if you're lazy to do too much sanding, cos it dries smoother than the quick type, but it dries slower. if u rather have it fast cure, use quick type.
