after some physical search and talking to shops, ordered this one
http://www.lawson-his.co.uk/bosch-gex-150-turbo-150mm-6-professional--p85413
yesterday , package arrived .. it has a big box.. and a bit heavier than I expect..
tested the sanding function with 1500 grid on scratch resistent laquer for some hours..
it erased all previous scratches that I caused by hand
and later tested polishing function with farecla G3 ..
results are stunning to say the least.. never ever seen any laquer without swirls
although for the polishing I was not patient enough so after some polishing used my rotary polisher to speed up the job but
really I liked it.. so 230 £ didnt fly out the window
and if you are going to sand and polish whole car with a scratch resistent laquer those machines are a must.. and whatever you do sanding by hand causes scratches and hard to remove with that kind of clearcoat
ps: dont believe in the ad its not quiet
