Yesterday I went down to the local ACE store to see if I could get some of that jig-a-loo. Lo and behold there's no way. Vendor out of business, can't get it or order it blah blah blah. So, I have a product on hand that should work but tests would be in order. Here's the rub, I have no test track, only a tuning board and am looking for suggestions on a way to test this product. If, and that's a big if, you wanted to check the stuff out i.e. looking for detrimental effects and or gains and were in my shoes how would you go about it? Maybe pin gages to check wheel bore before and after using for deformation of plastic. How about checking a comparison between jig-a-loo and this product. Your suggestions are appreciated. Thanks in advance for your input.
