According to my Profile, I've been a member since August 14th, 2002 (which I had to look at!)
Yes, since then alot has changed. My biggest "gripe" has been the demise of some very good car-products due to VOC-compliant regulations (like Meg's #16 wax not being sold in the United States anymore).
New sealants and now coatings have been a real game-changer in ease of use, durability, and shine, although I still very much old-school and love the look of a good carnauba wax.
Micro-fiber pads and more powerful dual-action polishers have really leveled the playing field against the traditional rotary buffers, along with newer compounds and polishes that take advantage of these techology changes.
But it is the contributing members who REALLY make the difference. I know that those of you who are reading this post can name some of those individuals whose posts have contributed greatly to your OCD (Obsessive-Compulsive Detailing) habit and the original poster, David Fermani, is just one of many I personally have benefited from.
Thanks for starting this peticular post. Long live this forum and its great members, both new and old.
(No, "Grumpy", you are NOT old, just greatly experienced, and willing to share it with us!)
