Just got the PE14-2-150. All that I can say is WOW it's so different than the 3401 in the way that it handles. Just an extremely well made machine. It has a lot of the characteristics of the Festool Shinex Rap-150.
I have 99% isopropyl alcohol from work that we use to clean fiber optic connectors with. I used this to make my IPA solution in a 36oz. bottle. I went with a 15% solution for now. I might have to back to 10% cause 15% might cause damage to the paint.
