    What's up with acrylic clear?

    i read in a few post that if you shoot acrylic clear, you have to super clean everything from the gun, spray booth and the oven. Is this correct or am I misreading what I'm reading? If this is the case, what problems does it cause? I just sprayed some about a week ago and I had a couple of issues with some wheels and a bumper. Anything to it or not

    I have used it several times in the last couple of weeks and had no issues using my normal cleanup routine.

      The only problems I have had were my fault and with black chrome. It caused spots in the final finish. I think it would probably cause these problems with any of the "chrome" type powders. Other than that I like it.

        I definitely like it. Plan on using it more and more. But I was wondering after reading about problems with it not being completely cleaned from everything. Thanks.

          Acrylic resin types are usually not compatible with other resin types. Companies who have reclaim systems and are shooting acrylic clear, usually have one booth dedicated to shooting the acrylic clear. The acrylic resin will contaminate other types of powder. You just have to make sure that you don't try to cross-link an acrylic with a different type of resin. By cleaning out your work space and your gun very well, you will help eliminate any type of contamination. I have heard that applying your basecoat and fully curing, then letting air dry, next re-heat and spray acrylic (this is if you can't get 2 coats to stick cold). This method tends to work.

            The only time I have second coat issues is when I forget the ground or to turn it on. Like I said earlier, after spraying the clear, I had some issues with a set of wheels and a bumper. Mirror Black and Wet Black. Just wonder now, if that was the whole problem?? I will see.

              I don't understand why one would use acrylic at all. Why not a normal clearcoat?

                The acrylics have excellant exterior durability, very good chemical resistance, but lack a bit in impact resistance. Probably the clearest of the clears.
                Some info on Acrylics toward the bottom of this page.

                That's what I was wanting to ask and always forgot. Where would be the places you might not want to use it? A set of wheels on a driver or off road type one? Maybe just on a show car that may and may not drive on the street? Mainly what do you think on using it for exterior type use?

                To me the acrylic is like the clear on your car/bike or whatever and its has to be taken care of in a different way than powder clears. Right?
