Wolfman plastic figure - Clearcoat question

If you are looking for a protective coat I would go with Polly Scale clear flat then brush some Future on the claws, teeth and eyes to give those items a bit of a shine.

I would have to agree with the previous comments in that you may not want to go to a gloss coat on everything. That said, if you do indeed want to use a clearcoat of one type or another, you can be relatively safe using an acrylic brand. Although I have read comments that contradict what I am about to write, I have used enamels and acrylics on top of one another with no problems thus far. There was an article in FineScale a few years ago in which the author used a base coat of one type of paint and then used the other for an overcoat to allow cleanup without disturbing the paint underneath. So far, I have used both enamels and acrylics as both the undercoat and the topcoat with no damage to the undercoat. Just some shared experience on my part.

Shine? Figures should be matt. Clothing, cotton, wool, hair, fur, buckskin have minimal gloss. Silk and satin should have a sheen. Leather can have semi gloss to gloss depending on age or be flat if it's well worn or sueded. Eyes can be glossed if they are big enough. The only figures that should be glossed are a very specific style of lead toy soldiers.
If this is the old Aurora mold form the mid 60's, IIRC, he's wearing only a pair of torn pants. The only gloss here might be on his teeth, if they're showing, and eyes. You could do his nails/claws semi gloss.
