Why not?
I never used to bother about cleaning, but never had a new car.
Two buckets seemed a cheap way to start and then it’s a slippery slope.
A clay bar was a revelation; seldom used, but always rewarding. Then polish, seal/ wax.
Never thought I was doing anything wrong...
Essentially a clay bar is used (as the final part of a multistage decontamination process) to ensure the paintwork is contaminate free prior to Machine polishing. There are so many different grades of clay bar, clay mitts and clay blocks on the market to cater for varying levels of contamination, not to mention different levels of paint hardness depending on the vehicle manufacturer, in short it’s a bit of a mind field and potentially dangerous if you’re using the wrong type of clay. Clay bars will damage/marr your paint, after all, you are wiping an abrasive putty over your paintwork to pickup/dislodge surface embedded contaminates and if the clay doesn’t damage your paintwork, the pickup on the clay will! Plus when you are using a clay, the paintwork must be wet, so you won’t know you’ve damaged the paint until you’ve finished and dried the paintwork, revealing anything from heavy swirls to hairline scratches.
Don’t get me wrong, I’m all for people looking after their own cars and I’ll always be happy to pass on tips and advice, but when guys watch a few vids on YouTube, go out buy a snow foam lance and clay bar, they call themselves “a detailer“ it is a little worrying. I’ve seen so many cars in my 16 years experience to know a clay bar in the hands of someone who doesn’t know what they’re doing is only going to end badly. Please also consider, that just because you had a fairly pain free experience with a clay bar, that doesn’t necessarily mean your mate (who you advise “clay your car mate, it’s so easy!) will go out and buy the same clay bar, use on the same paint and have the same type of contamination as you.
If you want to keep on top of any contamination as part of your wash process, then get yourself a good tar and iron remover. After washing the vehicle, spray Tar remover on to the lower sections of the vehicle (where you would normally find tar spots) and leave to dwell, then spray again and wipe over with a clean microfibre cloth, then rinse. repeat this process panel by panel, avoid spraying on to unpainted plastic mouldings And trim as it can sometimes stain. Then spray the vehicle with iron remover, if it’s a warm day do a panel at a time and ensure the product doesn‘t dry. Also avoid using in direct sunlight. Leave to dwell until you see evidence of the chemical reaction (purple runs) between the iron remover and the metal particles, then rinse. Ok this will not remove 100% of your paint work’s contamination, but it’s a much safer option.
Hope this helps?
