random orbital sanders/polishers for use with air compressors - Saxperience

would a random orbital sander/polisher for use with an air compressor do the same job as a UDM/PC?

do they work on the same idea so that you wont burn the paint?

apparently they are faster but more dangerous if you don't know what you are doing, so i wouldn't do it and use a UDM if your not sure

i use a variable speed grinder with the polishing head from a body shop suppliers about 70 quid i think inc vat what size compressor do you have at the moment

has anyone tried it?

would it even work?

actually, come to think of it... how would you attach the polishing pads as i doubt they have the same fittings?

i've got a 50L 2HP compressor.

a random orbital sander/polisher is completely different to a grinder though.

i havent seen any with accurate speed control so that may be a problem?

its enough for small jobs, i've already used it.

your right though, it may run out of puff trying to polish a whole car unless you did it very slowly but its not like you polish a car quickly. it takes time.

i just wondered if it was a cheaper option before i blow £150+ on a proper polisher. i think i'm just going to have to bite the bullet and buy it. i'm going to need it as i plan on doing quite a bit of spraying soon.
