Spraying Aerothane

Wondering if anyone has used a 3M Accuspray gun for spraying Poly fiber Aerothane ?? How well did it work ??Thanks.

I have that gun and have used it with decent results. I much prefer the lex-aire gun from axis products with a 1.0 nozzle for aerothane. I have worn one out and am on the second one in the last 20 odd years. A few parts would actually bring the first gun back to 100% ( nozzle,needle, etc.) but I use it for poly brush and poly spray. I use a 4 turbine HVLP unit with the lex-aire gun and get great results with about 40% reducer depending on heat and humidity. The lex-aire gun blows air even when not triggered so control of the gun is important (where you point it). The Accuspray gun is a little more complicated to clean because of a more detailed dis-assembly and re-assembly. The last lex-air bought I think was north of $300 but I am used to it and really like it. Wish I could tell you more about your question but it was some time ago that I used that gun and prefer the other.

Thanks...
I'm doing a fairly large repair and looking for a cost effective gravity feed gun. May only be a one time use.

I may have one of those. I have been using the Graco setup, and so far have avoided catalyzed paint. Let me look.

Cub Yellow it sounds like i may have given you some useless info. My Accuspray gun is a one quart non-bleeding suction type gun that I used on my 5 stage turbine. Not familiar with the gravity type gun with that name. Sorry about that.

I have a friend who runs a high end collision center and flies a Cessna 205 which he rebuilt and painted. We were sitting around a STOL contest and got to talking about spray guns. He said the shop only uses the Accuspray guns. When they get worn the get used for primer.

Aerothane is no more difficult than standard automotive catalyzed acrylic enamel. (Which auto shops have left in favor of basecoat/clearcoat, which is hard to screw up) Surface prep perhaps a bit more important because it's urethane. My cowling looks fine with a $50 1.2 throwaway gun. I use cheap "HVLP" gravity guns that use shop air at 40 psi.(at the gun, trigger pulled) I have long cruddy hoses so water filter and gauge on every gun. (in addition to a run of black iron pipe from the comp to the air dryer) With good prep and the right reduction, slam dunk. I worry about everything except the gun. Do test panels until the reduction is right. I love Aerothane, from what I read, I have no interest in water based anything.
