Hey All,
I tried casting some tubes that I had powder coated.
I used high gloss black PC on the tubes, they looked awesome.
I glued corks in the ends, then glued the corks to square pieces of wood. Next I put them in my mold and mixed up the resin.
I used Silmar 41. 4 drops of catalyst per ounce. Degassed before I poured. Poured them and put them in the pressure tank for about 20 hours.
When I took them out, they looked great. I went back to get them ready to turn a couple of hours later and...
They look like there are air pockets between the tube and the resin. Not bubbles, larger spots, allmost like the resin is starting to seperate from the tube.
Any ideas what went wrong?
The only idea I have come up with is maybe I should have used flat instead of gloss powder coat???
Any help would be greatly appreciated!!!
