I’ve normally done all my cleaning/polishing by hand, but I’ve heard so much good stuff about these machines. I managed to get a returned Meguairs DA220 machine from Amazon Warehouse at less than half price, complete with all the bits. It appears the box has simply been opened and the item returned. Normally I use Autoglym products, but I understand that only their silicon resin polish is suitable for use with a machine polisher. I’ve got one pad at the moment, but I would love some advice on what is best for this machine, despite a request to Meguiars they have not responded. I’d like to finish with HD wax, but like everything, it’s good foundations that make for a good finish. I don’t expect to use the machine throughout the cleaning process.
