I may not totally understand...but, will give it a shot. Instead of buying brand new cans...head to eBay..or gas show and buy the cheapest cans you can buy and then just use them to wrap with your Polly Wraps....I am not sure how "transparent" your wraps are if the real can will show through the wrap...Not sure if you are making your own wraps, but I would encourage you to make sure they have a date or say "reproduction" in small print on the back somewhere. Otherwise some people may think you are trying to make fake cans....
