so umm..yeah..i race alot on the smooth concrete and sidewalks...and i notice everytime i pick up my car..i see some black "junk" stuck to the bottom of the front of the car....
looks like dirt or something...ive seen it before..
and before i had put tape there to protect the bottom from scratching..
but....HOW DO YOU REPEL THIS DIRT STUFF!!!

is there anything small i can attach to the bottom..like any thin material or something...
heh oh yeah...my car has alot of clear tape on it...tape over the engine, the bottom of the chassis where the engine is, the bottom of the front etc...it helps keep the car cleaner by not letting debris in..
