Is the spray tape quite thin? I purchased the BFS, was not thrilled with it, I have seen the liquid tape but not in spray form. I assume that when you say you apply 3 coats you let each coat cure before coating again. As far as the brushes you mentioned, that's a big quantity but I paid more than that for a package of 10. Thanks for the tip.
Yes Ray, it is very thin. And yes, I let it cure, but only for a few minutes. I just let the loco continue to run to help with curing. I have used this method on AF steamers as well as on the following AM locos: GG-1, Northern, Pacific and J3a.
It is indeed a big quantity of brushes, but I go through a pack of 100 pretty quickly since I use them for cleaning, painting and gluing.
