Made some progress.  The passenger side is almost complete.  Working on the trunk area then the wheel well which has undercoating on it.  Then on to the other side.

Had a few pieces to remove that were getting in the way:

Braces – before:

Needed to go back over the firewall bracket and rocker edges:

Rear frame rail and trunk:

Will go over the trunk area one more time, then focus on the other side.  Then will go over one more time with some wax & grease remover on paper towels before stripping it down to bare metal.

Did a little more scrubbing tonight – still more to do on this section.  There is some baked on oil that is being stubborn.

You can really see the oil stains when it is wet.  This might take a while (several sessions).

Got a little more done on the floor after work today.

I still need to go back and hit the braces.  Having a variety of scrubbing brushes and maintaining a good supply of hot water definitely helps!

Made a little progress this weekend.  Started scrubbing the bottom of the floor.  Used a bucket, pump sprayer, and brush.  Also combined a little PurplePower in a few times.  Slow going and sore arms!

Making progress:

Happy with the results!  Getting an idea of what the rest will take and about how long.  Also, it will be better to do it in a bunch of shorter sessions rather than all at once!  This is the passenger side rear seat area.

Next will be the front half of passenger floor:

I wanted to get a head-start and an idea of what is required.  Still more to do, but progress.  Also had to go buy some more brushes.

This is going to take a while to clean!!!

I have been researching tools for removing the undercoating.  I have narrowed it down to 2 tools:

This is one: Dent Fix DENDF701 Metal Blaster Mbx Kit
You can resharpen using a grindstone and running in reverse.
Course wheel for undercoating
Medium  wheel for heavy rust
Fine wheel for paint

Here is another idea:

I plan on giving both of these a try – luckily, I only need to work on the wheel wells and not the entire car!

Made a little bit of progress this weekend.  The weather was nice on Friday, so I took the day off to roll the Camaro outside and power wash the floor.  The Camaro was on the rotisserie which enabled me to move it outside.  The one issue is the front half of the garage has bad cement on the floor.  I was able to use a pry bar to persuade it along in the rough spots.

I was able to determine that my car only has undercoating on the wheel wells and not the rest of the floor which will make it easier to strip.  I still need to clean it with some PurplePower and Wax & Grease cleaner before stripping.

From the back of the garage:

Getting there!:

and she is outside!  Went nice and slow going through the garage door as it was fairly narrow – suggest having 2 people to keep things straight if you are doing this.  Ready to power wash!:

Notice the leaf blower which I used to help dry the car faster.

About a half day to move it outside, power wash, dry, and move back to it’s resting spot.
