Hi guys. I was actually going do do a little guide at some point but i'll pop in some tips here.
Leeds, the soft clay is one of the best you can buy. The reason for this is if you claying ou want things to be absorbed into the clay rather than sit on the surface. Then refold obviously. This is the main reason that I always do 2 hits of Tardis on the car then a new step of ironx/deironizer you don't have to do this step but the tardis is a must.
Claying started out as a contaminant/fallout remover for sap ect.. so really it should only be used to remove miniscule particles of tar that maybe tardis hasn't picked up. Of course this isn't a problem if you're going to spend 3 days correcting your car but if you're not then you're essentially making the car worse by dragging tar particles accross the paint causing marring.
Even Polished Bliss when they use a more aggressive clay for some overspray or serious fallout, will show picture of how the clay has inflicted marring but they know they are able to deal with this.
Aggressive clay should only really be used in extreme cases and 1 a year. Soft clay like BH's is usually used every 6 months I would say although I try to do it once a year if I can.
I always wash the car, tardis/wipedown, 2nd hit with tardis/wipedown, rinse with the PW, ironx/deironizer, then give it a quick 2bm wash or a quick snowfoam to remove the residue from tardis/ironx.
This is important as those will ruin your claybar quickly if left on the surface.
After washing/rinsing just leave the water on the surface and then do a panel at a time claying and constantly spraying lube using light passes with the clay. Just never ever use pressure even if you see a piece of tar. Just go over it lightly, refold and go over again. Wash and dry before polishing and as you know the paintwork will feel like glass!
I know it might be time consuming but when giving advice I can only give it in a best practice way without cutting corners. It's also quicker in the long run as you'll be spending less time polishing!
Jay you don't fancy sending me a spare Zaino bar to try? Need it by Sunday though!
