I can't remember reading anything about how many RBs to use on a wing. It's just something I have learned over the years and never had any problems with them. I have also never though about the price of something like RBs in other countries. This web site is a true eye opener for me. I can go down the street to my local drug store and buy a box for almost nothing. I don't use them on any of my planes but I go through a lot of them when I'm building. Now I will think about it a bit more when I'm just cutting them off and tossing them out. I would like to know what the prices are for these in other countries?? I'm heading to the store to buy a bottle of alcohol, 91% for under $2.00 and a box of #64 rubber bands, about $1.50. Just wondering.
