Haha, i think that the question for newbie like us for the first time using DA
I even PM gfwong / blurcase / slk for this problem , DA tend to easily STALL !!! And as i have same machine as sifu gfwong, so asking is that i got faulty DA from clover
After this i understand that DA mostly wont spin if the panel is curve even how i tilt and adjust the angle and it will only stall , so now i understand using 1 machine actually cant be done for whole car especiall modern car with alot of special curve
https://youtu.be/aJPZmUlAdAwI recently love to see white detail jim video, now i understand and found that the Large throw DA is for when u using for large flat area , while if u are picky for the edge area , the Mini DA which have 3 inch pad come in very handly, especially Pillar , lower bumper and tight area (rear panel near the car plate) do check out how White detail Jim do paint correct, he mostly use small machine doing edge, then only move to large DA for middle correction, he make me feel wanna get the Mini DA in future because the 3inch pad really really come in handly , from he video i mostly see he use the mini DA more than the large DA
Another option can come handly is the Rotary machine with extension (save cost , else u need buy rupes idris which cost a bomb) , the extension can fit from 1inch to 7inch pad, there is a small rotary machine from shinemate too that slk recommend to me with weight 2kg+ only , can fit 1-3 inch pad with extention, but i stil not so pro in polishing, wait i familiar and pratice more with 15mm DA, then i will only figure out what i need and what i want
Just stick with one da, one rotary.
The rotary can switch between 6,5,3,1 inch. For 1 inch, get the extension , safer.
Buy so many machine better I structure an investment with capital appreciation for you
