Ive now had a chance to use these clay sponges on several cars. Over all Im very very happy with them but.......
Initially I was very dissapointed as it marred the heck out of my white Toyota paint and I even tried 5 different clay lubes with no pressure what so ever. My next car was a Toyota Prius and the same thing!
But after trying the sponge on a couple Mercedez , and a BMW I found absolutely no marring and it really speeded up the clay proccess and made it soooo much easier !!
Just beware of Toyota paint although I had a Toyota Avalon white pearl with no marring Yesterday.
Like I said I am actually thrilled but use this sponge with caution if your not going to polish afterwards.
Thanks Mark ! You made my work life a whole lot easier!!
