ABSTRACT:
A propane fuel storage tank having a fuel-containing tank body with an outer printed sleeve made of linear heat-shrink plastic material heat-shrunk in tight fitting encircling relation about the tank for preventing viewing of surface imperfections in the tank beneath the sleeve. A method of making and reconditioning propane fuel tanks is disclosed which includes loosely positioning a sleeve of such linear heat-shrinkable plastic material about the tank body and exposing the plastic sleeve to a temperature above its heat-shrink temperature to cause it to contract and tightly conform about the outer perimeter of the tank. The sleeve preferably encompasses a central cylindrical side wall of the tank, portions of the upper and lower semi-spherical end walls of the tank, and the lower foot ring, which results in a like-new reconditioned tank without the necessity for complete removal of surface imperfections and prior adhesively applied labels, or the need for complete repainting of the tank.
