Now this was a decade ago but I almost exclusively used One Stroke Colormax White for everything. Was pretty creamy even on cold days and never had any bleed issues on 100% poly. The company told me to try it on 100% nylon with the catalyst and WOW! It looked so fantastic on bags and jacket even after one hit but always doubled up. I'm not sure of the quality now but back then it was by far the best white I ever used.
lol Our shop in the winter used to get down around the mid 30s on really single and teen digit days but was usually in the mid 40s and my god trying to get the ink out of the buckets was a choir and mixing it was downright impossible. I snapped a few knifes trying to get ink out.
