I cleaned my mates old astra with my G220 and it worked really well, someone else now wants their car done, but this one is a 2004 model and I've seen a lot of you pros using Paint Thickness Gauge. I am not going to start cleaning everyones car so can't justify buying one but concerned if this is OK to use the G220 on the new car.? just in case your intestest its an MX-5 I got the Menzerna set (RD3.02, 106FA, 85RD) and blue, orange and white pads from Polished Bliss, on the astra I just used the final finsh RD3.02 / white pad. I'll get before and after photos but just after some advice if this will be OK with the G220, which Menzerna one to use on which pad. there are swirl marks. oh and its only the body work iam doing, he clean the inside.
