"I bought an Apollo HVLP 1500. Overall it is good, but too cheap in come respects. The paint I was spraying removed the enamel from the can. I had to clean the can with paint stripper down to bare metal to avoid contamination with black paint flecks on the job. Secondly the air control valve was affected (ruined) by the paint solvent. I got the gun working again by making a new valve out of brass. With these modifications in place, the Apollo 1500 is good and does everything I want of it. It would be wise to improve the material selections for the paint can ( don't enamel it and save some money!) and to make the air valve spool out of something more durable rather than plastic.
If you have to have a black coloured can then use a black anodised finish - this would be solvent resistant. The can does not need to be coloured on the inside does it?"
