Hi everyone - can anyone give me some suggestions of a good automatic waxer/polisher - nothing big and heavy, something I can handle (have a rotator cuff issue so need an automatic) - I've looked at a few online, but they seem quite big and cumbersome. Also - does anyone use a synthetic sealant first, and then finish with Carnauba? I've heard you can combine the two since Carnauba is not as long lasting as the synthetics. I know this has probably already been discussed, but since I'm new to the site, thought I'd ask. Thanks.
