Not sure this fits in the "gunsmithing" section, but since I read a few threads about this topic here I am taking a chance and posting it here. If the mods beat me in a corner, I apologize in advance :rolleyes:

I got from another CGN member a sweet deal on a SKS fiberglass jungle stock, and I want to paint it to desert tan. I have little knowledge of how to prep the surface. The fiberglass has a bit of cosmo/oil or whatever that stinky stuff is that the chinese paste on their SKSs, so can I use varsol/mineral spirits/thinner to get this off without killing the stock itself?

Then I can lighty sand it with (220grit?) and then go to primer?

Before I prime it I want to fill a seam that runs along the back of the stock, since it looks like two pieces of fiberglass glued together. What kind of filler can I put in the crack before I prime?

The paint and matte I can finish with, its the before part that needs detail :confused:
 
degrease with solvent then wash with soap and hot water. the seam can be filled with any quality bodyfiller. clean up any imperfections with filler. sand the filler with #100 grit followed with #220 and#320. primer and sand with #320 untill smooth, final sand with #400 and paint away.

Good tips, thanks.

Fiberglass is not afraid of solvents or water? Obviously not soaking them, but I cannot damage the surface or the threads with mineral spirits and hot water?
 
just a wipedown with solvent, one wet rag and one to dry. hot soapy water will ensure any mold release is removed and will not affec the fiberglass.
