well this is what I do.
1-wash and clay
2-removing swirls and scratches
3-polishing (to remove the swirl remover
and leave the paint CLEAN)
4-sealing (usually requires a few hours curing time before waxing)
5-wax (no curing necessary)
**optional** 5-.1 Seal the wax with FX100 sealant Glaze
6-425 (I think it works better with FX100) I can't really think of another product
that performs the 425 function.
