David,
Looks like the line is expanding!!
Formulate a plastic polish/conditioner for paint films and you should have a winner! These new films are unusual, softer, and when warm, MF fibers stick to them like mad! I don't know of anything that can improve or repair these films since they are so soft.
Engine Cleaner: Anything close to the "Euro" versions will be nice. Besides if it's really bad, APC+ or anything else like it will remove the really nasty stuff. But one for "casual" cleaning is a good start!!
Sealants: Never can have enough of them!!
Wax: Added protection for those still not willing to go full sealant or just have to have that can in the hand...Good idea, as long as it makes it nice and deep/wet looking as other waxes do, but adds that longevity factor into it.
Scratchbuster? That must be some pad!! Careful or you'll get some novice with a PC or rotary and one thinking they can remove a deep scratch. Scratch is gone...along with the clearcoat, base coat and primer..

On a serious note, a good aggresive foam pad that can have the same cutting level as wool w/o the haze or risk of burning is a good thing to look at. Some foam pads claiming to be cutting pads are just not right, nor do they finish well even with finer compounds/polish.
Getting ready to pull the Porsche into the lifts for a full detail one day. It will be top to bottom, and that's a whole lot of bottom under the car! The pan will be done along with all suspension etc.(Sonus Motor Kote) Finish needs work, damn black is softer than usual for Porsche, look at it the wrong way and it will marr up on you. Need to touch-up a few rock chips as well.
Still loving the Sonus Leather Conditioner! Really like the feel of the leather after treatment, feels non-slip. Best is still opening the door and getting that new Porsche leather smell again w/o additives to overpower it.
As for the "Top Secret" stuff....I'll keep an eye out.
Regards,
Dino
