TiO2 on top of UK 3.0?

[DetailerNewbie]

I've read that TiO2 may do a little better with water spots than UK, but I want the hardness of UK. I would like to apply UK 3.0 and then TiO2 on top of it. Do these two coatings play well together or should I stick to the same coating?

Topping UK with TiO2 has been done and there is no issues. You may also want to consider Gliss as another option topping over either coating.
