I ordered the Acryl-R with the applicator from Airstream.com, and used it last week to re-do the seams above the decorative strips, lights, hatches etc. This totalled about 250 feet of seam-sealing. The "oil-can with trigger "style applicator produces a stream of sealant about one millimeter in width, without requiring masking tape to produce a neat effect. The level of skill required is similar to that required to produce a neat result with a frame gun and a cartridge of caulk. One improvement is that the sealant ceases immediately the trigger is released, whereas frame guns are more difficult to control. I was able to produce a very neat and unobtrusive result, very quickly. Any imperfections I dealt with by using disposable gloves and a delicate wipe with a finger. These seams are too fine for Vulkem, and Parbond would have required laborious masking, as I only have it in toothpaste style tubes. I highly recommend this applicator and sealant. I noticed today that the Airstream.com site is offering the refills, but not the applicator. Perhaps they are temporarily out of stock. Nick.
