I have a question. Does anyone have any knowledge of anyone attempting to use color enhancing sealers for stone and tile to bring out the colors on a fossil? I did tile installation for about seven years and we used it to bring out the colors in travertines and such. It gave the tiles a "wet" appearance, without the shine. I know it wouldn't take the place of a consolidating sealant like Vinac or Paraloid, but it might make the fossil stand out against a matrix, if the colors of both are similar.
Just a question I've had, bouncing around my skull for awhile...
