I know about Finishline's and Sata's, but can anyone give any good or bad feedback on these Mac paint guns? Mac SG 1300 series. http://catalogs.shoplocal.com/macto...cularid=14579&pagenumber=16&uniqueid=16877130 It's on "sale" but I don't know anything about them. It would be used mostly for sealer and primer, but ocassionaly for base/clear or single stage. So I guess for everything but poly primer.
