Hi Dee Bee,
If you are using Hammertone out of a can it can vary between brands, I don't know why but some cans give a better finish while others are just a pain to use.
The W-71 Iwata gun that I use is a 500 ml touch up suction gun while the W-77 is a full 1 litre colour gun. I mostly use the 71 because of the points that Gadge eluded to. The amount of air and paint they shoot is all related around the set up that the gun has. The air cap, needle and nozzle are all part of the critical amount of paint that the gun lets out the front. If you have a No. 3 set up it will use quite a bit of product while a No. 1 set up will give you a finer finish which is more suitable to touch up jobs.
BTW it's not my intention to make you feel bad as that's not my MO, but there are very few Green ID tagged Model 45's in circulation that it would be nice to see a faithful restoration and also it will keep the value of the machine up higher than a modded machine. I guess using the following analogy would be a Monaro restored to original concourse condition opposed to a tubbed out pimped version that's suddenly become worth nothing.
Cheers,
BB.
Samson guns were good in their day but I've always been a fan of Iwata and Devilbiss which is what most Automotive painters used and was their weapon of choice. Now they've all gone to gravity feed guns and this is mainly due to paint costs being so astronomical, so every drop counts and wastage is kept to an absolute minimum, also cleaning is much cheaper as well. I must buy myself one soon but their prices aren't exactly cheap for a quality unit.
