Meguiars #7 ?

[mr.c]

Feed back please Hi,
Can some one tell me what the advantages are to applying #7 after
80/83? What would the benefits be? Also after 80/83 if I go to #7 then#21 would it be worth it to apply a carnuba or just leave the #21 ? If I did apply a carnuba then I guess I couldn't add layers of #21 after the carnuba?
Thank you for your time.

#7 just fills in any fine swirls and imperfections in the paint. You could not layer #21 once you've put a carnauba on.

As Jen offered, #7 is a filler product with added oils. Great between polishes and carnauaba waxes, not good if choosing a sealant. I dont find it needed when using the Pinnacle waxes either, as they are quite wet looking.
