I heard good things about it. Expensive but durable apparently.

Product Description
If you want truly permanent protection for your paint that leaves an incredibly glossy and shinny appearance the Optimum Opti-Coat 2.0 is your answer. This product is like nothing you have ever used before do don't even compare it to a sealant or wax you may have used in the past, this is a truly permanent coating applied to your clear coat or paint for serious protection. It utilizes a special resin based coating similar to what your clear coat is made from so you can expect it to last for years just like you would your clear coat. It's actually harder than most clear coats so it should resist scratches better than the clear coat. The protection is truly unique and best of all you don't have to keep re-applying it. It is actually a versatile product as well that can be used on your clear coat, painted surfaces, smooth plastic trim, bumpers, head lights, tail lights, wheels, chrome, aluminum, etc., but do not use it on glass.
Version 1.0 (aka Opti-Guard) was originally only available for professional detailers, but version 2.0 was designed to be more user friendly so it's now available to the public. While available to all the product should be reserved for those with lots of high quality detailing experience and those comfortable executing the directions listed below. It's critical that you work on a clean surface that is free of surface imperfections. If dirt and swirls are left behind you will be locking them in beneath the Opti-Coat. To remove them you'll have to clay and polish the paint just like you would your clear coat. After you have applied the Opti-Coat you generally don't have to clay or polish but you can if desired. The formula is designed to help release contaminants better than the clear coat so a clay bar should be needed less. If you want to remove the Opti-Coat in the future you'll need to polish the paint. Sealing and waxing is no longer needed but you can add a coat if desired.
Directions
1.) Wash and clay the paint so it has been thoroughly cleaned
2.) Polish the vehicle to remove all surface imperfections
3.) Wipe down the paint with 15% mix of Isopropyl Alcohol and distilled water to removes oils, etc. from polishes
4.) We recommend putting a rubber glove on now so you don't get any product on your hands. Put about 7 to 10 drops on various parts of your foam applicator to help prime the pad, but you only need to do this once in the beginning.
5.) Apply several drops to the foam applicator and buff it on nice and thin up and down and then side to side.
6.) Within five minutes inspect your work and make sure no areas look too thick, as they should look clear after they flash. If it looks too thick use a foam applicator or a microfiber towel to buff out imperfections. The surface may feel a bit tacky so only do this as needed. Generally the less you touch it after the application the more likely it is to cure perfect, although it is a self leveling formula that will help with minor imperfections. Work on one panel at a time before repeating this steps 5 and 6.
