Started mine. This is a Hi-Tec Composites stock from NZ, which are similar to Stocky's.
Couldn't get textured spraypaint locally, but found a 'granite effect' option. I was skeptical about how well it would do, and while some of the prominent bits flaked off, most remained, and provide a texture similar to a wide-pattern skateboard tape.
Went with Rustoleum truck bed liner for the grip and forend; I lightly sanded back the granite paint underneath first, in case it didn't bond to the small flecks underneath well.
Partway through painting up, with the baselayer completed and a camo pattern over the next couple of days.
Key lessons:
If I was doing it again, I wouldn't keep the same masking tape line for the truck bed paint - three layers have formed too high of a shoulder, and this is a potential peel point. I think I'd either mask up the first coat, and then re-mask it further out for the susbsequent coats of the truck bed liner, so that it's graduated, or just not mark it up at all, painting it roughly where it needs to be, and figure it will be covered by the top paint anyway.
Top-coating the granite effect paint worked will for 'securing' the prominent parts of this paint. Rather than flaking away, and taking the top coat with them, it seems to have worked the other way around, with the top coat sticking the prominent 'granite' parts down better.
On the flipside, the topcoat has so far smoothed out the texturing of the truck bed liner - so, ironically, there's more grip on the main part of the stock that just as the granite effect paint underneath, and the grip and forend have ended up not being as textured. I'm not too worried, as this was an experiment anyway, and I'm sure will still work fine in the field. Also, my experience is that clear-coating adds its own kind of texture, which is very non-slip (at least, the brand that I've used).
'Naked' stock first, then granite effect and truck bed combo before painting up.
