Larry,
more power to you man, I dont think anybody is telling YOU not to do your thing, my whole point is to share , based upon my experience, what I believe to be good and valid information to help other people from running into stumbling blocks. If it works for you, then more power to you like I say.
BUT, I have experimented enough to know, that I dont like to experiment when I have a proven, reccomended method, and based upon my experience, I will do things as reccomended by the guys that got paid millions to research it. for ME, and MY airplanes, the cost of a tack rag, is cheap insurance, just like the cost of a high quality spray gun, high quality thinner, and proper application. even with all the right stuff, things still go wrong, thats why I posted my experience ( see the link I posted) with using alchohol as a solvent. because I have had problems with it, and it cost me LOTs of hours to repair.
as I said, you do what you please, but dont get offended if everyone doesnt agree please. It works for you, great, I am not going to come into your shop and insist you do anything.
good luck and above all, have fun
