I recently had back surgery so i cant wax by hand anymore. Ive been looking around for a inexpensive alternative. I cant really afford a true polisher but i came across this Meguiars DA Power System. Is it worth the money? Ill mainly be waxing with maybe some polishing. The products i have are Chemical Guys Extreme Depth Liquid Carnuba Wax and Deep Relfections XP. I'm open to any other suggestions towards machines. Thanks for any help. Also needs to be lightweight. Price point around $100 if less would be better.
