First I disassembled, then I washed everything with a mild detergent. for some parts I used a hand held media blaster just to get some of the areas that needed a bit more attention (didn’t need to take it all down to bare metal). Finally I sprayed them with SEM Trim Black 39143... stuff works great! Now the grills are no longer concours because I chose to paint the sides of the chrome ribs in black instead of the stock Argent... wanted it to match the tail lights. After spraying the chrome ribs black I used 0000 steel wool to remove the paint from the chrome... this also polished them in the process.W
hat did you use to get them that clean i have a 69 that needs them cleaned up.
