A couple of questions if I may I would class myself as an "amateur enthusiast" (not an enthusiastic amateur) when it comes to car cleaning and detailing. My normal routine is a weekly rinse off to remove worst of Muck hand wash (2 bucket method) using Meguiars wash and wax rinse off application of Autoglym Aqua wax dry off and buff In addition at least twice a year both cars get a polish Autoglym (SRP) and a coat of Meguiars Hard Wax.. The cars , a 2 yr old X1and a 3 year old G30, come up well, water beading is impressive etc, very little swirling, but I am noticing a bit of contamination / tar etc on the paintwork. Overall I'm very happy with how the cars look, they have never been to a car wash and dealers are instructed not to wash them I'm contemplating next year trying my hand at "claying" the paint before polishing and waxing Questions If I clay the cars will it remove the existing layers of polish and wax ? Am I better simply trying to remove the bits of tar etc using a tar remover? Am i likely to damage the paint in any way by claying it ? I've got visions of dragging a piece of tiny iron across the bonnet? I've no desire to spend hundreds of pounds on ceramic coatings, or really expensive polishes / waxes etc, but are there other reasonably priced products I could try or suggest as Xmas presents ?
