I would like to know what brand of acetone is the best to use with paraloid b72, or if they are all the same. I would also like to know how to mix it, and what percentage of paraloid b72 to use. The fossils I find here are often very dry, brittle, and have cracks in them. I would like to use the paraloid solution to coat the surfaces.

I have recently received this Palaeoniscus freieslebenensis from @Strepsodus, and it has some kind of coating around the fish, the matrix is slate and I would prefer to have it without this coating but I don't know if I can remove it, and even if can should I do so or would that risk the integrity of the fossil?

I am quite new to preparing and preserving fossils and am not very knowledgeable on resin coatings. I have been told that Poly Methyl Methacrylate has some similar properties to Paraloid and can be dissolved and used to coat fossils. Is there a reason it is not used for this purpose? Thank you very much for the info.

I only prep with hand tools at the moment so I can rarely get all the matrix off a fossil. However, when wet, the matrix is usually impossible to see and the fossil looks very well prepped. Is there a coating I can use to keep the fossil looking wet? I’m looking to try this on trilobites in particular.
