Underbody of 72 cutlass

I have refinished all the suspension parts and frame with either paint or powder, but now i am unsure of what to do under the car. There is a ton of tubber undercoating and grease. How should i remove the grease and prep and paint the underbody?
Thanks, chris

Hey Chris, a couple years ago the TV show MuscleCar cleaned up the underbody of a Camaro they were restoring. Here's a link to what they did (skip to about 11:20 on the timeline):

Those guys used spray-on engine enamel on their underbody, but Eastwood sells a spray-on rubberized undercoating that you might also consider.

When my Cutlass was at the body shop they removed all that under-gunk with hand scrapers and wire wheels. It took a lot of time and elbow grease and left a big nasty mess on the floor, and they had the body on a rotisserie for easy access. We went with a custom finish - they sprayed the underbody with Line-X tinted to match the body paint color.

Just a couple ideas for you to consider.

I had rust free floors on a 71 I'm finishing up. someone though years ago decided to "freshin it up" with spray can undercoat. I used heat gun and scraper first. Then always use a wire knot wheel on a 4" grinder. Then I 80 grit da sanded the whole thing. etch primed, then satin black the whole thing and then duplicated the factory overspray patterns. My car had original green paint all over but the undercoating was a mess. very time consuming.barefloors3.jpg 20442/progress18.jpg[/IMG]
