Tangerine HT pads and D151 leave a good finish in my experience. Good cut from that combo too. Menz Power Finish is 203 correct? Try that with HTs also. Bit less cut but finishes down really nice.

Just finished re-modeling our master bath about 3 weeks ago. Gave the glass doors on our new shower a coat of Klasse AIO to aide in future cleaning. Did the same thing with the kitchen cabinets last...
BMW 750Li. I didn't mind the massive panels as much as the 23 miles of champagne-colored leather inside. I'm still tired, and that was something like 4 months ago.
Chenille from Advance. Around $2 if I remember right. 9 times out of 10 I don't use it, but one of my regulars in particular has a set of 28" wheels on his Yukon and the mitt helps a great deal.
Any word on durability from the sealant/wax portion of the Finishing Wax? I'm guessing similar to D151, which I've never known to last more than a few weeks all by itself.
Ultima is kinda interesting. It says "free rinising" and "leaves no film" but it seems to remove the beading aspect of your wax and replace it with a sheeting effect, sort of like...
Out of all the "gentle" or "ultra fine" grade clays that I've used I've yet to see one that doesn't leave any sort of marring. Not saying I've used them all by any means though.
Just as the title states, do you need a dedicated metal sealant for underhood use? Specifically things that get quite hot, uncoated, polished valve covers and a supercharger for example.
