did you thin it with mineral spirits, rustoleum is great out of a gun.thanks. on this I used Rustoleum oil enamel in sunrise red which I read was very close to the original color. won't use it again. I don't feel like it is very good out of a gun. I usually use Sherwin Williams Industrial Enamel which is very good and has better abrasion and impact ratings but you have to buy a gallon and all I needed was a little over a qt. the turbine HVLP is the way to go. no compressor needed, very little overspray as it is low pressure and best of all does not pick up the humidity from the air like a compressor does which is a big deal in florida. mine is a 3 turbine model, now they have 4 and 5 turbine units. not sure what the advantage is as mine works fine but they are supposed to be better.
nah... try mineral spirits.I thinned it with acetone which is what it calls for in the tech sheet on their website.
BTW this is what I used to thin. sprayer manual says for oil enamel thin until the viscosity cup empties in 25 seconds. (not my photo).nah... try mineral spirits.
edit: that's funny, they used to recommend mineral spirits. I just went and looked, and they now recommend acetone on the web site for thinning, but further down, they say that mineral spirits is the solvent... I have old can's that I probably need to throw out, and it says thin with mineral spirits... F'd up.
the new can's say mineral spirits or acetone, I would not use acetone as it would evaporate too quickly. I am looking for it to lay out nicely, and I have to believe I would get a little orange peel if I used acetone. I don't think it would ever go on too dry, since it still has it's own mineral spirit solvents and needs to dry .. but the MS as a thinner works very well.
