Time is everything. How much time does it take to roll up the plastic, store it, un-roll it vs just using clean, new plastic right off of the roll?
Do you get several different sizes left over in your trailer waiting for the right size hood to re-use them on?
When I drape a hood, I stretch it taut which tends to leave stretch marks, as well as I make small holes in the plastic to insert the chemical wand to spray the hood without letting any of the chemical splash/ blow back on me.
So when I get done, my plastic is a one time use situation.
I've heard of people using re-uable tarps, but when you clean a couple of BK's, you're not going to be reusing any plastic or tarp.
