so, ive been using the GG6 for years, I started with the old model unit it quit and then sent it in and they sent back the newer version. due to these years of use the GG6 has really just become an extension of my arm.
i own
G15
G21
Flex 3401
GG3
porter cable
rupes 21
each has their own ups and downs but for me its still always the GG6 i go for. ive tried really hard to stick to the new BOSS polishers, forcing myself to like it and want to use it and they are great machines, they really are but for me with the 5 inch vented backing plate, the BOSS pads, MF pads, LC flats or any other the other pads i use on a regular basis you just cant beat the GG6. im going on i think 3 or 4 years with my current model and i cant even tell you how many cars its polished but it has never let me down. it really is a great machine for a beginner, hobbyist or a professional.
