I received a buffer for Christmas and wanted to try waxing my current car with it before doing a trial run on my X that is coming. It came with two bonnets. One is thin (terrycloth?) and the other is thick and poofy (lambswool?). Which is used to apply wax and which is used to buff? (Sorry if I am offending any 'Zaino-freaks' out there...I haven't ordered any Z yet.) Do I hand-remove any excess wax before buffing or does the bonnet take care of the excess?
