Ok. I realize these may be elementary questions, but I take great pains in asking questions even on the basic levels. Anything I do on my Blazer, I wanna make sure its an actual improvement and not taking steps backwards. So, I have a couple questions. 1) Under hood insulation - too keep or not too keep. What is its purpose? Is it truely necessary. Mine is looking kinda ragged and I know when they get wet or what not they are heavy and look like crap 2) Debadging - I actually posted this question in another thread of mine. To take off the fender badges and the ones on the back quarterpanel, what is needed? Are they bolted on somehow? Id like to remove them without destroying them. More questions will be added as I think of them.
