I can't remember who recommended Groits for cleaning and wax supplies but I ordered the leather Care kit and Best of Show wax from them.

I got to use the leather care kit today on my 03 Surf seats and man, that stuff is GREAT! The kit comes with a horsehair brush, interior cleaner, leather care conditioner, leather scent spray, and two applicator detail sponges.

The seats are softer and more beautiful than ever. I used the Maguires leather cleaner before but the Groits is much better.

 

That is good to know about their leather care products.
I only have experience with Lexol for my steering wheel cover, but I hear it works great.

As far as their products for the exterior, I have been using the BOS wax, clay, Speed Shine, and polish for a few years now with the Porter Cable buffer.

I like Zymol, the two bottle kit...Cleaner and Cond.
