*Chickselog: The first set meaning:

1. Wash
2. Clay
3. Step 1
4. 3M IHG
5. 3M SCLW

would give you better results, if you made a pass with wax on a dirty surface, clay could still remove those particles embedded. And this procedure is better since Step 1 is designed to prep paint to accept a sealant or glaze. If you use Step 1 and then clay after, claying might actually dull the gloss and finish Step 1 provides, so stick to the first pattern, it would give you a better and glossier shine.
