I was wondering if anyone could suggest a good primer? I've been using Krylon Grey primer since I started building/painting kits, but on my last couple of kits, I've noticed it actually has a bit of a visible grain on the kit, which kinda bugs me. Seeing beautiful, sculpted details covered in little grains? If I can avoid it, I'd like to. If anyone has any suggestions, as to whether or not I should try a new brand of Primer, or if it's something I'm doing wrong, I'd appreciate it! Thanks, guys!
