I'm clueless about that. I was just thinking that you wanted the slick, "look ma, no gaps" look. Ya know, this site is filled with truly brilliant types, and surely someone has the answers. The clearest epoxy I ever tried seemed to be RAKA and with that, I've told you all that I know. Usually, the MSDS provides the answer as to the chemicals that make up the mix, and from that the answer can be found from TOMES, CHEMTREC or the like.

: Is there a clear filler available? I am thinking about products like '5 min
: epoxy'. They are pretty viscous and mostly clear. I wonder what makes it
: thick?
