So the question is when layer the bottom layer is less durable than top layer what effect will that have on a sealant.
Thanks for the PM about this thread, I didn't see it when it was posted...
A real popular combination for a lot of people is to apply a finishing wax or a finishing sealant over the results from using a cleaner/wax or cleaner/sealant.
My opinion is applying a second coat of anything ensures,
Uniform coverage which equals uniform protection
Uniform appearance, which equals a great looking finish
So "yes" applying BFWD over BTPnS would increase durability. The most important factor for the durability of ANY car wax, synthetic paint sealant or paint coating is how the surface is "touched" down the road.
For example there's a huge difference in how long any protection product will last when a car is carefully hand washed versus run through a brush style automatic car wash.
