I've had the same issue. I've tried using both Satin Sheen and Super Sheen as resists, following the video instructions on Tandy's website, with both Antique Gels and Hi-Lite colors. The Super Sheen had *slightly* better result for me, but not to the point shown on the video. It didn't seem to have quite the same luster when used as a block with the Antique gel over it, It seemed somewhere between the Satin and Super sheen on the finished project. I've been careful to let each application (both color and resists) dry 24 hours before applying the base. Personally I'm applying the color (either Cova Colors or Hi-Lite) and resists with an artists' brush, then using a soft cloth to apply the base color. If anyone has tips on this subject, I'd love to hear them too!
As far as the NeatLac and BagKote, I haven't used either so I can't give you any advice there, sorry ^.^
