SMC,I'm in need of this type of spray gun.Looking at Porter Cable's PSH-1 on the net and was wondering if this is a decent gun to spray metal objects such as old machiney and parts.The paint I will be using is Alkyd paint that is thin w/xylene,(Industrial Paint from S&W).I don't know what size canister is on these guns,but I'm thinking maybe about 20ozs.Also,I notice that different size tips are available,what size should I look for?I think that a 1.7 comes with this gun.I do have other sprayers,but they are the 2qt type and I think that in this application clean up would be eaiser.I have never used a gravity feed before,so this will be my first purchase.Not looking to paint a BMW,but I do want something that is in the middle or alittle above far as quality.Maybe it would be easier to say 75.00- 125.00 range.I do have a compressor that puts out 16 cfm's.But in the past to help keep from pushing the cfm limits I have always thin the paint to make it flow alittle better.Thanks again for any advise,brands,tip sizes etc. Carroll
