Are BF2 and UPP sealants abrasive??

[TCL]

tcl, my tahoe is metallic, charcoal metalflake, the SG made my car look sterile. When applying the UPP over SG the look became darker in appearance. I have since placed a second coat of UPP and the appearance is even darker. I think it brings out the metalflake.

Thanks for the input. I think to be safe, I'll apply it on one section first. That will give me a good side-by-side comparison with the BF2.
