This week it was one step forward and half a step back.
After waiting a full week as I said I would, this morning I masked everything with 3M blue painters tape (2+ hours) and shot the yellow on (3 minutes) and removed the masking while the yellow was still wet as I always do (10 minutes).
The tender was a disaster: the yellow went on well, but the masking tape pulled big chunks of the red paint right off when I removed it, despite my taking care and using a light touch with the painters tape: Rustoleum double gloss red does not stick well to Rustoleum metallic silver. Anyway, I will let the yellow harden for a week and then red-spray the red on the tenderusing a non-stick stencil technique for the masking - easy when it's just a straight line. No big problem, just annoying.
The loco came out well. A small amount of red over the drivers was pulled off with the masking tape but I can flow on a glossy match to color and sheen by brush. There are several other minor touchups, but I am pleased with the look. I will do that next weekend and then apply the single black line (between red and yellow) with pinstripe tape, then neolube drivers and rods and pilot trucks, etc.
