What ever you can't take apart by hand with a bit of muscle you should put the fire raptor in a bath of degreaser, such as purple power,simple green, etc. Let the components soak for a few days, and then hit em with a soft brush. Don't worry about the resin weakening, I've had forge world stuff sit in paint stripper for months without any compromise to it. Resin and metal figures have to be assembled with super glue, and a lot of that will peel off along with the paint. After you are able to strip off the components, you should be able to start fresh with little to no trouble.
