SRP? is that a 'done' thing? I do detailing, but don't follow detailing world atall. Good work there btw.
I find Menzerna gives off a lot of dust which is a bugger to shift (I know Menzerna is very popular with detailers though), I prefer the Sonus SFX range which gives equal results and less dusts (so far better in my opinion). Doing an S2000 or any car with a hood, less dust is a must.
