Not too bad, but just remember your target market. Those people might not know what paint sealant or clay bar is. Of course you, and the other people here on the board know, but probably not your average Joe. Focus more on sensory words and adjectives in your flyer. Things such as: "Your paint will shimmer after advanced 4 step method". Of course you don't want it to sound too hokey and infomercial-like either. Try and find a good balance.
Also if you're putting out flyers in a certain area and see someone tell them "Hey the first person that calls on this street/neighborhood etc. is getting X discount." Once you get a foothold and Dr. Snooty gets his car done, I'm sure many will follow.
Also remember if your flyer is only going to be used to get them to go to your site, mention your site has coupons, discounts, or specials (and have lots of pics of course). Also rotate those specials frequently and put an expiration date on them to get people off their cans and call you. Good luck, hope this info is useful to you.
