I like the hydrotech pads 5.5 inch. Just 3 different pads to work with, very easy.They don't soak up product like some other pads. Less saturation and more product stays on the pad so you know what you are working with. The pads are not thick so work very well with a simple da like my GG6 and with less saturation the pads do not get heavy. So with these two features, there is no bogging down.
I just did my Dodge durango a week ago. The paint was in good condition. I just used the crimson pad (red) with WG finishing glaze with about 25 lbs of pressure to do some very light cutting and and then eased up on the pressure and kept on going polishing with the same pad. Other pads you may have to use two different pads to do the same task. Then turned around and used a new clean same crimson pad to apply the WGDGPS with no pressure. Spread was easy and no real saturation. I used a gray ccs pad to compare and the ccs pad held more product because of the pockets, so you can do a very large section when spreading a sealant like Wolfgangs, but personally I did not like how that worked out, it seemed too much. I like how the hydrotech pads gives me more of a control feeling. Then you can turn around and use the same crimson type pad to apply wax (no pressure) also. I have a red ccs pad that I am going to compare against the hydrotech crimson pad to apply fuzion wax.
So you can see why I like the hydrotech pads. With one type of pad (crimson) I was able to do some light cutting and polishing under the same process with one pad, turn around and apply a sealant and wax. A lot less hassle for me to use than to decide what 3-4 different pads to use.
