Worm trace fossils

[Fossil61]

i have some great worm trace fossils in sandstone. they look so much better when wet but when they dry out not so. is there a way i can prep this soft sandstone to look wet or just to make them stand out more...many thanks

Maybe a little wax on it? It brings out the colors a bit and it’s not definitive.

Thicker Paraloid B-72 can also give a 'wet' look.  I use about 10-12% wt/vol ratio (for a thicker, 'wet' looking varnish), which means 10-12 grams of Paraloid for every 100 milliliters.  Maybe not the best way of mixing, but that's the way I've always mixed paraloid and it's worked well for me .   @Ptychodus04 has much more experience with B-72 than me, he probably has a better method for you to follow

My method is generally less precise. I’ve mixed so much of it over the years that I estimate the ratio based on observed viscosity. 
 

The mix ratio is somewhat irrelevant after the 1st use as some of your acetone evaporates the moment you open your storage container. 
 

This being said, Jay’s advice is sound. A thicker solution (or multiple applications of a lower concentration will look “wet”.
