On Paper these look like they perform well, but what about in the real world.

Does anyone have any experience with these coatings? 

i have read great reports about them, but preparation is the key to a good finish as your sealing in whats below and if that is swirls and scratches then its protecting those.

There is a couple of members on RRSport that have gone for the best on the market GTechniq Crystal Serum and a year later and trips to the Alps h's car looks brand new, though it is a proffessional application job

I bought Wolfs Chemicals Hard Body, for mine and that gets good reviews but as normal i just haven't had the time to polish and apply.

Gilfrishman used it on his FL2 and he said it was great, there is a sample pack which gives small bottles of three products, which were Shine & Seal (polish to pre the paint) Hard Body (Anti Scratch coating youre after) and Rim Seal (Wheel Sealant)

They don't seem to sell this pack but do one which includes a coating for Trim, instead of wheels

Application wise it reviews were alot better than some, for DIY, which is one of the reasons why i choice it Former Mod/Member, with the most post & Chicken George Arch nemesis
