Just got my freshly painted grille back!!!

Hey everyone just got my grille back. It has only taken 4 years.... The 1st business was doing the job in trade for some date coded glass of mine they put in some megamillionaires Mr. Norms Gss restoration. Thankfully that megamillionaire bought out that resto shop, and created a new "Hot Rod shop. The stand up crew he has there were nice enough to give me my unfinished grille back. So fast forward 3.5 years, I drop it off at my buddies custom motorcycle shop. He finally finished what the other shop never started, to the tune of a whopping $100.00. It looks awesome, all black epoxy, has a satin finish. Sweet!!!! Now I just need to finish the resto...ie polish the lens covers, and headlamp buckets and brush all of the stainless that i will reinstall. Yeah I said brush....no polishing for me...I want it to be different. So my question, which will also apply to my taillamps... what type of paint or even brand if you have something dialed in, do I use to paint inside the marker lamp bezels? ie the reflective rear portion of the lamps! 2nd question where is a good source for hardware, clips, push pins, springs etc to finalize my grille restomodification? Thanks everyone. I'll post some pics tomorrow!
