HI,JOHN NO I JUST USE THE COVERS THAT CAME WITH THE KIT. TO MAKE THE WHEEL WELLS A LITTLE MORE NEATER LOOKING I USED 7-11 PLASTIC COFFEE CUP RIMS (CUT THEM OFF ABOUT A INCH AND FIT THEM IN THE LARGER WHEEL WELL,ALSO WILL HAVE TO CUT TO FIT OUTSIDE DIAMETER THEN GLUE IN PLACE) ANY EXPOSED RAW WOOD WAS PAINTED TO PROTECT FROM EXHAUST OR OIL PENETRATION.
