To be honest, Im not a fan of the silver GMC logos for a few reasons...Mainly though, it looks like GM forgot to finish their emblem...it looks like just a silver template or background piece..and most of them dont have the same depth as the stock emblems (silver ones look very thin)...however, thats just my opinion...plenty of others do like them...and if you like it, thats all that counts..(lots of people hate my red grill..but I like it..thats all that matters)
by the way...when I painted my stock grill (although with a different color, the process is the same)...I used scotchbrite pads...scuffed the hell out of the grill trim...broke the grill inserts out since it doesnt snap out, scuffed that piece...cleaned both pieces, sprayed both pieces with automotive primer, paint, and clear....then epoxied the insert back to the grill trim
Just go wild with it...have fun...and ALWAYS remember...its ONLY a MATERIALISTIC item...a bunch of metal and plastic...Its not the end of the world is something doesnt work out!
