The undercoating will probably be done by Vintage Car Works when the Elephant Racing spring plate stud supports, and upper rear shock mount supports are welded in. You will see to some extent the bead around the outside edge. I don't want it ground off. I will clean up the melted undercoating. The grinding marks will be covered. I'm confident VCW's will be able to match an spot in the undercoating. After that a few thousand miles of small pebbles and road dust it will look fine. The only way you'll see the bead is under full wheel lock after you get down on your knees. Whoever ends up with this car down the road, I'll want them to be able to see that area has been streghtened.
