Low End BC under High End CC

[ragtop396]

After reading many posts about the painting options is it recommended to put a less expensive base coat under a high end clear; the thought being why waste $$ of the base since the Clear is where the ultimate quality/gloss and UV protection are..... Will the Base still fade? I've heard it may take more BC to cover.

For Example - Would you use PPG's Omni BC under their high end 2021 Clear?

Thanks.....
