RE: How do I cover with Silk?
Hey, Spud.
Within the last 1 1/2 years, I have used Aero Gloss over and under; Sig, Randolph, and Certified with no problems, and yes it will go over nitrate. I did a test panel because I only needed a little of a color; Aero Gloss was readily available, but nothing else was.
The green stripe in LG-01 (several posts earlier in this thread) and the black are both Aero Gloss over Certified.
