I am lazy and want fast results, my go to products are generic magic erasures(50 pack under $9), Meguiers synthetic x spray wax(can be used on everything, even interior) and can get in gallon for like $20. Rest of what I use varies, but those 2 are great for multiple things and cheap. Meguiers wheel brightener that you dilute, works out to like $2 a bottle when buy in gallon jugs. I use HD 3D speed for polishing, easy off and takes out swirls, fine scratches. Wax varies for me. Meguires synthetic Xpress spray wax is excellent, leaves no residue, can do everything on car/truck, inside and out, smells ok, can use after wash as drying aid, on Windows, plastics etc and lasts forever. I gallon jug lasts me a couple years.
