Last night, I coated 2 waterputty and 2 ultracal30 molds with Devcon 2 ton. I put about 1/4 inch of Devcon in the bottom of a little pill cup. It was about an inch from each of the tubes in the Devcon.
Into the Devcon, I put 6 drops of rubbing alcohol. The drops were obtained by dipping the end of the paint brush into the alcohol and then letting one drop run down the stem and into the devcon. I also added 2 drops of red food coloring. The mix seem to drip off the end of the brush freely after stirring.
I painted as thin a coat as I could and still see red coverage. This morning, I went to look at it and one obsorbed the devcon and the other three have a very shiny coat. I coated two molds with the mix above and then threw it away. Then I mixed another batch for the second two. The first batch produced the dull and a shiny finish. I did the dull one first.
Question: Did I put enought alcohol in? I expected more obsorption. I tried to put the thinnest coat I could on each mold but the shiny molds seem to have lost the detail. They look great and feel smooth but I think the baits will have the shape of the mold but a smooth finish.
Any comments? Dave
