This is the fossil I’ve been prepping for the past three months. I applied B-72 Paraloid over what I’ve been able to expose in preparation for an acid dunk. Here are the after pics. I’m a little disappointed because some places of the fossil were destroyed by the acid. I used a 5:1, water to acid ratio and it turned out to be much stronger than I anticipated. BUT, many locations where I applied the Paraloid remained in tact. #fossil
