I've restored the steering wheel in my BMW M5 using these methods:

1. Prep 7.7
2. Cleaner 3.8
3. Rinse 3.0
4. Acidifier
5. Hydrator 3.3 (24 hours)
6. Fatliquor (48 hours, refresh in between)
7. Hydrator 3.3
8. After 96 hour drying, 8 coats of Microtop-54D
9. Protect with Protector-D

My question is about the durability of the microtop-54. If properly cared for, will I have to re-apply the microtop-54 again in the future or is there some type of maintenance?

The wheel is absolutely factory fresh, it is dull in shine, no longer sticky or greasy and is a pleasure to use.

Thanks for any information.
