      Re: silly question

      What gun are you using? Parts do not have to be pre-heated to lay down powder the powder particles are charged through you gun and attracted to the part + to - ...send me your email address and I will send you information on powder coating...

              the green high temp tape will not melt under normal curing temps .
              i never used the optiflex but both guns i use the older model gema and the wagner give similar results
              you will have to practice and try different settings to see what s best for you but a good starting point
              would be to set both the kv and the miliamps at 60 for most jobs , very large flt areas you can raise to 80,
              complex shape you lower the settings , second coats try 40 or 45 kv for a start.
              with my gema i can do 6 coats with no problems.
              for air adjustments you adjust to have a nice unform powdercloud with no puffing or spitting with just enough pressure push that powdercloud over the part , but you don t want the air pressure to blow the powder off the part .
              do a few tests and tell us how it turned out

                the machine iam using is gema optistar type cg07 the settings i allwas use it on are set to
                flat surface
                50 , 4.0
                00 , 00
                0.1 , 0.3

                i ment aswell see if the green tape is still on the wheel wen ive masked iand shot the second colour do i put the wheel in the oven and start to bake it with the tape still on will it not stick to the 1st colour of powder ?
