I think that is what I'll do and that is to coat a really thin layer front and back and scoop coat the extra off and let that dry. I'll coat a a thicker layer on the shirt side after the 1st coat dries and dry it shirt side up let it dry and repeat.
The only capillary that I've found that thick is super phat but at around $33 a screen I think the extra coats of emulsion is my best option.
