I've been using alumilite amazing clear cast for my cups and I've done about 20ish and haven't had really any problems. But on my last two cups I've turned I got a crazy amount of dimples. Does anyone know why that would happen? I haven't changed my process. I use a small heater, always clean off the cups before starting, use gloves, clean mixing cups.

I have found that brushing it on too quickly can cause very small dimples. It is so thick that it can bridge over a spot that will later dimple.
Another thing is possible contamination. Make sure you're cleaning with a strong alcohol.
Any idea how old your product is? Alumilite lists a shelf life of 1 year for ACC.

Another thing - have you shaken the bottles lately? Sometimes the mixture in the bottles has "settled" and needs a little shake to "remix" it. Just like Italian dressing, sometimes you need to shake it a bit to get it back right. I personally have taken to the habit of shaking (or in the situation of the mold material tubs - stirring) the bottles for a minute (then let them rest for another minute) before I start using them for the day. And sometimes I'll shake them if I stop working for an hour (like lunch time). A thick coat can also cause a bridge over even if you're brushing it on slower. Sometimes you can fix a dimple by adding another layer as the resin is "self leveling" but I'm not sure how well that would work on a curved surface.

It works quite well when using some form of rotisserie. I usually sand between coats, but I'm a bit obsessive. You probably don't need to as long as the surface is very clean. |

Good to know, I don't have anything like that (outside of the kitchen rotisserie roaster) but I do like to learn. And by calling it that, you've given me an idea of what I might could use (kept separate from food stuff of course) if it ever boiled down to needing one and can't find the right machine.
