Hi just to add, I have had my own car Valeting business for some years now, have always used srp/radiant wax and HD Wax on various finishes and with the correct prep have always had good results, this is where it ends how ever. For correction of paint defects, swirls and holograms, I have been using the 4 stage process of 3M profet it 3 range. When used correctly with new or used paint and using the matched heads and cloths it gives the best depth and clarity of any paint finish I have ever seen. Far superior to any autoglym products and I have tried them all only to be disappointed. I would recommend to anyone 3M for detailing and paint correction, then HD Wax or wax of your choice to finish. Autoglym make good prep products however, clay kit, detailing spray, tar and glue, all great products, but as for there polishing products I find them dated when comparing them to megs and 3M. So to round up, autoglym make nice prep products, cheap and effective trim/plastic and tyre dressings, not so great paint polish, unless you want to be out there every week! In my opinion I would have a professional detail your paintwork once or twice a year, then use the correct cleaning methods and waxing methods to keep the paintwork swirl free for the rest of the time,
Just my opinion but I have a lot of customers that would agree
