What are your opinions on the clamp-on verses bolt-on skid plates? I just received a Baja Designs with steel clamps that will certainly eat away at the aluminum frame. Steel in direct contact with aluminum creates "dissimilar metal corrosion". I could insulate the clamps with rubber or send the thing back for a bolt-on. Also seems like a time consuming hassle for maintenance, messing with all those loose clamps. Thanks.
