TOPIC: PMMA for body modification

I was just starting at one of my nodules, that's one of the last cosmetic residuals I'll be having touched up, and couldn't help but think what if PMMA could be used to create an even dispersion of hard nodules along you penis so you have a textured Cock.

What does everyone else think of this?

Actually I have heard of this too, but not with PMMA. Some people will insert stainless steel ball bearings under the skin.

Do you have any links?
