I just finished my home made fluid bed and it's working fine. I saw that Stump Hunter just finished his also. Mine has got 4 fluid beds on it so I won't have to change cups as much. I just tried out two of them, one with chartreuce and the other with white and they work good. I found out that after you dump your paint in and open air valve, you need to stir the powder for it to bubble correctly. I'm getting a thinner coating of paint on my heads now.
