Thanks for all your advice and wisdom. Now it is a choice between Brodak and Sig. I will try to stay away from Aero Gloss as they are starting to reduce their variety. I plan on brushing the dope on after I clean the surfaces, so I do not care if it is available in spray can or not and I do not have a ventilated area in my home to set up a spray booth. The odor from brushed on paint is so strong I can only paint with the windows open and a fan blowing. That limits my painting season here in Minnesota to about 5 or 6 months (when I should be flying). The rest of the year is construction weather. Have you had any experiences with these dopes (as far as I know they are both dopes). Both are available by mail order but Brodak is not available in the stores while SIG is. I heard of some stories about finishes cracking or yellowing with age, but I didn't hear any Brand Names mentioned. Not to belabor the point, but which would you recomend? I think I have used Aero Gloss all my model building life (about 45 years) whenever I painted. I have some experience with SIG and it seems to work OK. Some of the local guys use Brodak but they have spray booths. Any opinion or suggestions would be welcome.
