Go back to Napa and pick up that "barrel" for 12 bux (its probably a box with a 5 gallon bag in it). That is EXACTLY what you need and what everyone is talking about- your napa guy sounds pretty inept

- there is no need for you to go outta town.
( if it is a bag, be careful when you open the tube, you'll have to cut it with scissors or a knife- it's a bitch. )
AND WEAR GOGGLES!!!!!!!!!
