Are you looking for extra durability ?? IMO. I would go with the 845 alone. Topping with the Megs. 21 is not going to give you anything more. You would be better off putting two coats of 845 on and letting it go. Beauty and Durability. Try the Duragloss mix with 845.

I have used the 845 after #21. You can do it, but I don't see any specific advantage over a single layer of either.

I think that the 845's solvent content will @ best mix the m21 in with 845.

I like your avi Danube. LOL

I'm interested to know what everyone thinks too. About a month ago I detailed an E class Mercedes and sealed it with m21 and topped it with colli 845 24 hours later. I didn't have any issues and i think it turned out great. Did a maintenance wash on it last week and the vehicle still looked great after washing. Beaded up something wonderful too.

Yes extra?? durability/pop something??? Im speaking specifically topped over M21 I know many people have put #845 over pretty much everything but I haven't seen anything with M21 as the base seal probably because it last longer idk im just wondering if its worth applying the 21 or?

You may want to look at Duragloss, their ad's say the "Wet Look". Depending on the vehicle color this may be all that you need. Duragloss and 845 give you the best of both world's. Looks and durability. I have not had any experience yet with the BlackFire product line, but someone may chime in with their experience.

Think Spring !!!

Be the test dummy and try it out. Then keep us all posted on the results. I used Megs cleaner wax and topped it with Collonite 476s on both my DD in Nov and they still look great and bead well.
