Re: 20 or 21

The claim on the bottle of any Megs "hydrophobic" products is that they "bead like crazy". They don't sheet very well.

I would think that sheeting products would require less hydrophobic activity so as to allow the water to pool together and then be repelled in a sheet, instead of separate beads, as UQD does.

I think #21v1 sheets more and beads less than #21v2. The same would go for the NXTs.

Re: 20 or 21

Is #21 also good for sealing painted aluminum rims ?

How many layers do I have to apply so that brake dust and the other grime easily goes away ?

Thanks !

Waxes and paint sealants tend not to last very long on wheels but if you're going to wax your wheels then one or two coats.

Layering does not exist on paint, at least no one has ever proved it so just stick with one or two coats of wax or a paint sealant.
