Welcome to the forum and it would get you off to a better start here on RT if you go to introduction thread and tell a little about yourself.
What did you use for paint on your P95? Did you strip down the gun completely and then paint it? Have you fired it yet to see if the slide and all are functioning correctly?
Hello and welcome to the forum. As far as your paint job, I have to agree with Shooter. There are various other ways to change colors if you so wish. Personally I like stainless or old fashioned bluing but we are not all the same and we have different likes and dislikes. And Buster brought up a good point on paint in the slide rails. Normally you want to keep them as clean as possible to the slide moves correctly. When you fire your weapon, a lot of heat is generated and could very well cause the paint to peel, crack or jam up the slide. This is just MHO so you can judge for yourself. I would caution you on when you fire that pistol, I would fire single rounds and check the slide each time you fire.
I am guessing it has been at least 2 years since I painted mine and it still is glossy and no chipping or peeling. I didn't like the stock crappy dull finish which is why I painted it. IMO It looks very good for a $50 paint job.
My Marlin model 60 that I painted at the same time still looks very good also.
