Used this with an old orbital buffer I found to wax my 19' molded fiberglass camper and it worked great. No swirl marks and mirror finish on a twenty year old trailer.This is nice quality and works fine on car without marking the finish. It is just a tad large but string adjuster makes it work. Looks like it will last too.I purchased this bonnet to use on a cordless drill to refurbish/polish my headlight lenses. Works perfectly on a low speed using lens cleaning kit productsThis is perfect for our old buffer especially with tie string. Thank you!I am very satisfied with the purchase ...... Thank youYou need a super thin pad to make this work. It isn't even close to fitting mineGreat productEasy to use - perfect fit.
