thanks for all the tips everyone, looks like a pretreatment and a gel stain is the way to go, Minwax says the gel stain will stain metal and fiberglass, and if thats the case, it should be able to handle pine.
I'll post update pics as its done, which might not matter as we've seen tons of them done already, and all of them look amazing.
