Hi all, I am new to the forum and I have a question =) I just bought a new FSR bullet red sparkle. It is a solid build and I really dig the color but when I opened it up, I found the shielding paint was very rusty and seems poorly done. I haven't measured the connectivity though (I ordered a multimeter but not arrived yet). I know shielding paint or copper tape are two common solutions. I prefer the copper one personally so I can do the work inside the house. The question is whether it's ok to put copper tape on top of the original paint? Conceptually I don't think it's gonna be a problem as both materials create a conductive compartment. Maybe I will sand down the old paint a bit so the surface is smooth. What do you think? Any suggestion is appreciated!
