Used 303 in Aug on my new '07 conv - it is really good. After visiting many sites, trying to find the "best" in use at this time, ended up going with the 303, and feel that after 4 months, this product works!

Expand on 303. What is it/who makes it. I havnt heard of it unless it under another name. I've been using Rejex for two years. No complaints from me.

The product "303", I found on Auto Geek. There I read about the ingredients of the product and who used it, especially Corvette convertible owners. I was really concerned about any product that had silicone in it as in my business, I find that silicone attracts dust and dirt nad eventually deteriorates most materials. Also I was familiar with "SUNBRELLA" cloth and 303
provides protection for this cloth. I ordered - from the web site 303 Products - HIGHTECH GUARD as it had no silicone in it. I also did all that was recommended as to cleaning and preparation, then put the stuff on. This was the first of August, and as of today, the water still beads after weekly washes just like it did when I first put it on. I drive a '07 Blk/Blk and feel REJEX and 303 are unbelievable. I feel lucky that I found these 2 products to keep my Vette looking like a Vette should!

Thanks for the info. I'll check their site out.
