I have just used the Surfix system for the first time and really love the results. I used the system on a small project and used a foam brush as the applicator (this worked well), however, the 150 pads were overkill. I have an RO 90 and thought I would use the smaller Vlies pads. However, I can't find the 90mm pads anywhere but the Festool catalog. Does anybody know if they are still available?
