Its funny you asked this question.
I have a Bear Brown Bear dual round wheel compound bow, with laminated wood riser and maple/fiberglass laminated limbs.
I had my riser drilled and an threaded insert installed so I could use a plunger rest back in the 1990's.
These modification hasn't hurt anything about my bow, and I have taken deer with it since the mod.
I want to paint it though other than using tape, since it has a gloss finish.
