just finished painting under carriage and fire wall this week with por 15 chassis black. it said semi gloss but it shows more of a flat look. would it look funny to paint the sub frame and all the suspension parts gloss black or does it look better to match everything under the hood? how does it come from the factory? not looking for factory look but did they use 2 shades of black also? hate to put my 70 all back together and be upset with the finished product. neighbors son is coming over to help me start a progress post of the work done so far. i am to computer dumb to figure it out. thanks for any replies.
