[quote name='Fallguy']ok so what type of prep is needed to apply IW845?
Same as any other sealant...a clean surface, either paint or clean sealant to layer upon. 845 is not an AIO.
Can it be layered ? What type of shine ? depth , wetlook , ect and what is a good QD for their products ?
It can be layered, I usually wait 40-50 minutes between coats. Re the look, everyone's eye is different. On my parents' 93 LeSabre, light gold color, it has a nice solid shine, some depth, a little wetness but that's not a primary attribute.
Is it a carnuba or synthetic?
Mostly synthetic with a small % of carnauba.
I don't know anything about their stuff but I also saw people mention 476 (i think) and I see the website has like 5 different wax types , anyone use the others ?
476/885 (same product) and 845 are both long lasting sealants that do very well in winter conditions in my experience. 476 is a little more durable, tougher to work with. 845's look is a bit nicer, easier to work with. Both most be applied THIN, I mean it, THIN, and the paint can't be too warm.
