I got some from Autogeek that work OK. I use them over my hardset foam pad on the PC. If I have a wax or polish on the car to remove, it may take 2-3 bonnets, depending on how thickly I applied the product, and what product I used. Sealants use less bonnets, and I don't always use the MF bonnet-s0metimes I remove by hand----depends on the product.
