OrionStang Posted August 4, 2013 Report Posted August 4, 2013 So, for a sealed box using polyfill, should I break the 'fill up and pack it loosely, or pack it in there tight? SMD Super Seller My Feedback Thread
Kevin M Posted August 4, 2013 Report Posted August 4, 2013 Loose I wanted to add that the pillows from wally world can work and are cheaper then a bag of poly fill. Some cats in HT toss the whole pillow into their monkey coffins. lol Here is an article in pdf. on poly fill... http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CDgQFjAA&url=http%3A%2F%2Fwww.nousaine.com%2Fpdfs%2FBox%2520Stuffing.pdf&ei=XbP9UbLMNYeirgHBhIDoDw&usg=AFQjCNFc7ynw2Rf74v2x-4uWEHhxBt1IqQ&sig2=KbTgmQ0MWbt9pmWknYvfKQ&bvm=bv.50165853,d.aWM 2005 Ford Focus zx4 AMT's and Planars 18" Infinite baffle

OrionStang Posted August 4, 2013 Author Report Posted August 4, 2013 Just a temporary box, Brian. I have the polyfill so I figure i'll use it. Box 1.1 cubes and I have a pound of fill. Still trying to decide on the box/trunk configuration. SMD Super Seller My Feedback Thread
