Hi Lawrence The unit is in three parts; 1/ The Unit itself 2/ The Sanding flaps 3/ The Brushes The Sanding flaps are extendable. The Brushes are changeable When I did my Delorean, the marks (gouges) were quite nasty on the doors and front panel. I only used the sanding flaps and brushes that were supplied and I did not have to extend the sanding flaps at all. If you mean how many complete units you have to buy I would still be able to get them for the price I paid. If you mean how spare flaps you have to buy afterwards, They would be about £15.00, I would think the condition of the car would have to be terrible if you needed another set. There are other people more expert about how you blend the panels. I needed the unit as I had exhausted all the avenues in removing the deep gouges. It was case of "if this does not work I will have to have them removed and sent away or buy new panels". I hope this helps Regards Kevin #5959 #10163 -----Original Message----- From: Lawrence J, Lormand [mailto:lawrencesr@xxxxxxxxxxx] Subject: Re: [DML] Proto 1 Looking for flap sander sanding Flaps How many at A time do we have to order?
