I have several concerns about some of the information on the thread..., not wanting to cause a "stir", but would like to add some important information to this post.
For example-
"With the new, highly complex two-stage clearcoat finishes coming out from automakers -- especially high-end manufacturers like BMW and Mercedes -- waxing itself is becoming obsolete."
Clearcoat is a paint, only with no pigment. As a paint, it needs the same protection as a single stage paint.
Without protection, whether by a wax or sealant, the elements eat away at the finish..., just like everything else. There is no magic in clearcoat that makes it impervious to the natural decaying process..., and as such, needs to be protected.
The clearcoat paint protects the base coat, but without a layer of protection on the clearcoat paint, it is going to deteriorate much faster than if it was not"protected"...,
" First, beading is not an indication of a surface that is protected."
True, a freshly painted car will bead, as will a surface that is polished such as a nice car finish, smooth counter top, etc.
"Beading actually isn't a good thing. The beads act as magnifying glasses that intensify the sun's energy on a tiny portion of your car."
Again, true. However, would you want the finish on your car protected or not with the intinsity of the sun on your car?
Many of the quality polishes/waxes/sealants actually contain UV inhibitors to prevent problems as described above.
The reason a finish will sheet, is because of the surface not being smooth..., just take a walk through a used car parts yard in the rain and see the sheeting action.
Nothing will stop the natural aging process..., but with protection, it can be slowed down..., at least for our cars
Millreef,
The protection for the new finish can be applied at home and save you hundreds of dollars and in most cases will yield a better protection.
There are a lot of good, High quality, easy to use protectants on the market with UV inhibitors and very durable protection.
My suggestion would be to apply the sealant or wax yourself. The car dealer uses professional grade waxes and sealants such as Pro, Auto Magic, Malco, Coats, etc, etc.
It is purchased in most cases in 1 or 5 gallon jugs for between $15 - $20 a gallon and is designed for fast easy use.
If you read the lifetime warranty, most have fine print that you have to get the protection applied every 3 - 12 months..., no sealant will last the life of your car. Sealants and waxes are only to keep the enviromental polluntants from actually touching your paint..., which is a good thing
