car polisher makita 9227c or porter cable 7424 which one is better and y? pls anybody can say

Not the same type of tool. If you’re new at polishing a car finish use the Porter Cable. You will get in fewer problems with it as compared to the much more powerful Makita. If you’re not good with it the Makita will burn through your paint before you can lift it, the Porte Cable will not, much more forgiving. The Makita sized machine is not required for anything less than the worst paint finishes.
