Along with the already mentioned rtfa, I should mention I am a chemist/materials...The real concern about these materials is the slowly accumulating data saying that there MIGHT be unforeseen medical issues with the particles used in the paint. As a substance, its invisible. TiOx is only White when its big enough. These are an order of magnitude smaller...totally transparent as long as the matrix material is. Otherwise: over time these materials will last longer and longer if they are used in a widespread manner as they will be able to bind the local discolorants and make them scoopable essentially....what some might see as a discolored paint should properly be considered as a akin to kitty litter. Replace when used.
