Actually I scrubbed it all down with a scotch brite pad. No sand paper.
The undercoat adheres to most surfaces without prep.
I had a little bit of time to work on the car today.
Got the wing and trunk lock reinstalled along with the side markers.
That's all for you Steven!!!!
Also did some work on the S14 diff, it has a cusco 1.5way and an s13 diff cover.
Painted it up with the BBQ paint because of the thickness of the paint (Rock chips and so on) and the heat rating being so high.
I have something special planned for the diff cover.
More to come in the next few days.
