"Sonic scrubber pro detailer brush heads" star star star star star_border Having now purchased 3 sets of the Pro Detailer brush heads, I find that I am mainly using the firm cone brush which works extremely well on multi-spoke alloy car wheels.This leaves me with little or no use for the other 2 brushes in each set. It would be very useful if you sold the different types of brushes separately, even if there were 2 or 3 to a pack would be fine, providing they were the same type. support_agent A note from the team Thankyou for your suggestion. We've passed it to our buyers for their consideration.
