I just cleaned the primary and secondary on my viper. A fair bit of dirt came off with Brake Cleaner, but I noticed that on the primary the surface is not completely smooth about a inch from the top. It feels almost a little bumpy to the touch. I can see what looks like corrosion or something. I was wondering if I used 1500 or 2000 grit sand paper on the primary would that be ok to smooth it out.
