Paul S,...most of my BF products are almost two years old, so I am still basically working with old stock. The combo of using BF polish, and BF Wet Diamond did/does cover over very minor swirls on two of my cars. Not a cure-all, but does hide at least a few minor flaws. Jag XK and Caddy CTS-V, were/have been improved by using the combo. Cat scuffs ...well...fell into a more noticeable "classification".
My older bottles don't really explain "good-to-go" finish parameters. In short, I have never known, what the actual time line is, between buffing, and hitting the streets. I have always been very conservative for repeat applications, allowing 24 - 48 hours, or more, between coats. I have only applied product late in the day, or evening. Buffed all off, then, driven cars as usual between coats.
Dean....Yes, the sealant that I was preferring to use is BFWD, mainly because I have the product on hand, and I have been happy with the finish (except for dust!). Because of the grit around here, I am more concerned with trapping abrasive particles on the surface, if said surface is not fully "hardened". As described above, I have always buffed the car(s), only by hand, within a few minutes of application, following initial hazing. I try NOT to keep my car outside for long periods, during product application/buffing because of concern for any possible settling of gritty particles on the surface.
The car will not likely see any rain, for many months,...as we have only had about 4 inches of total rain for all of 2012 so far. Our desert system typically has very little rain over winter, unlike a Mediterranean climate (think southern CA).
Dust/grit, and extreme UV are our main enemies. Static is a nightmare, which also tends to attract even more grit.
Haven't had a chance to re-apply product from the new tube of Scratch-X. Or apply any other product.
