Have the Grit Guard Pad Washer and for water based compounds and polishes, they are great. Usually just fill mine with water and use Pinnacle XMT Polishing Pad Cleaner, and pads come out good as new:props:
If it was me on the first order, I would use AGO and forget about the 15% off, Shipping is $21.99, would save you some $$$$, unless you want the free gift.
