Check your liquid lsp's beading without a glaze under and you will see what I'm talking about. I too initially thought all my glazes didn't have any adverse effect on my lsp till I noticed beading quality and duration not to be what it once was. But heres something very interesting I found. Meguiars Deep Crystal Polish,#7 Mirror Glaze and Ultimate Polish which are all filled with Meguiars trade secret polishing and conditioning oils did more for looks and darkening paint than any glaze I have ever used and own. Best part is it actually helped lsp's bond! Kind of like the oils dont prohibit bonding but actually promote it. Loving using the Megs stuff before any lsp.
