Speaking of Randolph, I just got a gallon of clear butyrate from Wicks.  It came in a paint can.  Is that standard?  I'd think it would come in a narrow, screw-on-top thinner can like Brodak does. 

That is the only way I've ever get Randolph clear. I haven't seen it in the thinner type cans in years.  The first time Chris Cox and I ordered Randolph clear all Spencer Aviation had were quarts so they gave us gallon prices.  I kept the cans and when empty, I clean them and refill from the gallon using a spout I bought at the Home Depot.

Hi Howard,

I have been using Randolph butyrate dope since about 1975 & it has always been packaged in round paint cans, both the gallons & quarts, colors & clear.  Five gallon sizes come in metal 5-gallon pails with a plastic pull-out spout.  The next larger size would be a 55 gallon drum (mostly for orange dope.) 

Interestingly enough, The current Aircraft Spruce catalog shows a gallon screw-on top can beside the listing for Randolph butyrate tautening clear, but they show a round gallon can beside the listing for non-tautening butyrate clear.  Certified clear comes in gallon screw-on top gallon cans & quart screw-on top quart cans.  The thinners for both are packaged in the screw-on top type cans in the quart & gallon sizes.
