Quote:For the most part there is a a great deal of proof out there that the “red/grey chips” that Jones et al based their paper on, are in fact a rust inhibiting primer paint with a Kaolinite base.
“We can also say that because Kaolinite is present and that it is embedded in a Carbon based matrix with Rhomboidal Fe2O3 that a more likely explanation for the red material is paint.”
