Hi, Guys - I know I`m still new to the board, but some of you already know I`ve been very interested in testing detailing products (paint care only). After reading so many false advertiser claims and users` unsubstantiated opinions, I`ve gotten even more interested in testing methods. How can we compare one product to another in a truly objective way?
I believe I have found the answer. There are standards (ASTM, ISO) for measuring gloss, and there are laboratory instruments for taking the measurements.
For a brief intro to the methods used, check out http://www.rhopoint.co.uk/instruments/ng-art.html (`http://www.rhopoint.co.uk/instruments/ng-art.html`)
I`ve looked into these meters - but they aren`t cheap - the "Novo-Gloss" meters start at about $2100. So - I`m looking for creative ways to solve this problem:
1) Anybody know of a company that might rent lab instruments?
2) Anybody know of trade associations or other places where these products might come up for sale used?
3) Anybody want to write me a check for $2K in exchange for my undying appreciation? :)
These meters would truly allow us to share information in a standard way. This would be a big improvement over merely expressing opinions! I should also add that even these meters aren`t a total solution. Some of you have noted one wax makes a finish look "sharper" than another, or one glaze adds more "depth". The definitions of these terms are vague, but i believe we do see differences. It is not clear, however that any meter can measure these effects. Still, I think we would learn a lot. Open to ideas (and contributions!)
