Shown on this page are the test results for the  metalwax products. As you can see the tests are extensive and the product is put through severe application processes. It is not just what we say about our products it's what the test  results show. Does your current polish have these tests on record?
When your dealing with Aero Space and Aircraft no one takes your word for how good your product is, it has to be Certified. Does your current Polish supplier expect you to take their word for how good it is or can they produce Certified Test Results?
This is important. The finish on your car,aircraft,motor home ,truck,boat is very expensive to replace. Do you know what it costs to re paint a 747-400 Boeing jet? That's why the paint and metal polishing used on these very expensive jet planes is certified and tested.
You should use them in your application and see a real difference.
