Gents - I've got a m77 with a black, synthetic stock that I had cerakoted in OD green (barreled action, trigger guard, bottom metal). I'd like to add a little green and brown using a sponge to the stock to break it up a little, but I was planning to just use the black plastic as the base. I've read all about prep, rotating the sponge, etc.

Two questions:

1. Is this a bad idea?

2. How necessary is a clear coat afterward? (I've got Krylon paint.)

Thanks!

P.s. would love to see pics of DIY paint jobs if anyone is willing to share.
