I was gonna give my opinion on this, but Jack pretty well has it covered. I have used R-M Pre-kleeno oil and wax remover for years and have never had a fisheye on anything. As far as mixing, just follow the directions. The people that made the stuff probably know more about it than we do. :lol: Jack's advise on the respirator needs to be well heeded. Any paint is bad enough, but when spraying urethanes and enamels with hardener, it's essential. If you read the label on paints like Imron, they tell you to wear an air-fed, not just a filter type respirator. Some of that stuff is just plain bad ju-ju on your lungs. As far as spray guns, I am following this with great interest. I have never used an HVLP gun. I just used the old school stuff. I found years ago that Astro makes some pretty good stuff for the buck. Had a Binks #7 copy. Parts guy took them apart and asked me which had better looking machining. I picked up the Astro parts and handed them to him and said"these Binks parts". I was shocked to find that i handed him the Astro parts. I hope Astro has kept their up. I know, I'll be flamed for buying non-USA, but I have to eat also.
