After doing lots of research, I ordered Paasche H. It'll complement my Iwata Eclipse, I hope. My plan is to buy a bunch of jars so that I can store primers, base paints & clear coats in them and use them conveniently.
Paasche jars are rather expensive ($5 per jar). Other jars are much cheaper (e.g., $18 per dozen). My concern is whether the adapter cap of other jars fits the Paasche H. Is the adapter cap (of the jar) for a siphon feed AB standardized? I've seen several jars w/ the adapter cap advertized as "universally fitting" on eBay.
