Dec 23, Lunchtime Update!!
Taking a short break to eat some lunch and figured I'd post a couple of pics...
Tass has been scrubbing hard on the under carriage... She's doing an outstanding job...
The factory sure wasn't worried about being neat with the bonding adhesive...
Can someone explain what this baffle-type foam piece is attached just above the astro vents... Mine is an AC car, so my astros are blocked... Not understanding the use for the baffle???
Removed the temporary rivets from the floor board and laid the glass to fill the holes... Also, filled the holes from the aftermarket cruise control that seemed to have been disconnected before I got the car...
Going out now to sand blast the pieces I removed from the under carriage... Tass is going to continue to scrub--Atta Girl!!
Thanks much
Rogman

Update, Christmas Eve 2011!!
Thanks to the guys that responded to my question about the rear baffle...
Vert Rear Plenum Baffle
More cleaning underneath today... The mother-in-law even got into the action today...
After I make a few fiber glass repairs, probably one more cleaning with dawn, hot water and a scotch brite and I'll be ready for the lizard skin application... Here are a few shots of the fiber glass repairs...
After Tass got done with the under carriage, she moved to getting the undercoating out of the interior...
Been sand blasting some parts, but wish I had a bigger air compressor to keep up... Can blast for about 5 minutes and then let the compressor catch up...
Will try to get out there for a few more hours tonight...
Thanks for looking

Hi Rogman16,
Been following your thread and work here and have a question reguarding the fiberglass repair inside your battery box. What is the advantage of the green tape?
Did you cut out the spots and re-glass them? Cant tell whats going on in the picture.
I have a spot in my battery box that will need attention when I get to it and I'm trying to get ideas on how to repair it.
Thanks and keep up the good work. I look forward to reading your thread.

Update, Christmas 2011!!
Well, spent most of the day in the garage, but don't have many progress pictures to post... Finished stripping the paint off of the rear of the car... Got some body work to do on the left rear quarter... Right side is pristine...
I'll be spending most of tomorrow working on glassing the seams and fixing the damage on the left side...
Thanks much for looking...

Update, 26 Dec 11!!
Boy, grinding out the factory bonding adhesive is very messy... I had two shop vacs' hoses taped to the side of the car to help with the dust... Finished grinding right side and got glass in the seams... Know I already have a couple of low spots that will need a little more glass, but overall, pretty happy with the first side...
Grinding:
Glass:
Shaving the Alarm (glassed in rear yesterday making it easier today to glass the outside):
Have to go back to work tomorrow, Bah Humbug!! Should be able to leave a little early each day as this week "should" be very slow all week...
Thanks much for looking,

Had to work a little longer yesterday than originally thought... Got the seam ground down and blocked... As suspected, have a couple of low spots... Called tracdogg2 (Mike's Awesome) and got his advice on how to proceed... Will get back after it tonight...

Update, 28 Dec 11!!
Well again, 4 solid hours in the garage tonight and only got two progress pictures to show for it... Re-glassed the low areas on the right rear seam... Ground out the seams for the rear panel and glassed them in... This took me 4 hours, go figure...
Going to shoot to do the left rear seam tomorrow, if I get off at a reasonable time...
Thanks for looking...

Update, New Years Eve 2011!!
After a 2 day break to watch my Noles beat the Irish (Thurs) and a family night last night, spent all day sanding the glassed in seams... For some reason, did not think it would take this long to get what I got done today...
I learned my lesson with low spots on the last go around, and I ensured that I would not have low spots this time... What did that equate to, longer on the grinder, a lot of elbow grease on the block, and a garage that it looked like it snowed in...
Well, I took my time with the grinder and DA, so as not to get carried away and grind too fast/much... Here's what it looks like:
After:
Is that the way the corner (for the bumper placement) is supposed to look on the 68-73 rears?? Posted separate question today earlier... That's the way it looked prior to removing paint and it didn't look like my right side had any damage... Just want to ensure the corner supposed to be a "clean" 90 degree curve versus mine being very sharp at the corner...
Bad news is this was the easy side... Tomorrow holds the left side which had damage meaning more fiberglass to sand (not just the seams)... Will try to stay focused with all the football games on the next couple of days...
Happy New Year everyone one...

Update, New Years Day, 2012
Finished the left rear that had previous damage... First lay of fiberglass was very, very close... Took about 4 hours of block sanding with 10' of sand paper gone off my roll... My shoulders are feeling the burn... Needed to lay one more layer right around the corner of the spoiler...
Ground out the left quarter seam, the front luggage rack holes, and the antenna hole (there were a couple of bubbles in the fiberglass so I ground it down a little to put fresh glass in there...
Now that "most" of the "major" work is done on the outside, I can turn tomorrow to cleaning up underneath to get ready for lizard skin... My original plan had me doing the body work once the body was back on the frame, but hated to lizard skin and "seal" the underneath and then run a grinder all the way through the skin and mess up all the work that I did to get the under carriage in tip top shape...
Here are a few pictures from today's work...

Looks great man. A little tip on the glass work - you don't have to get it dead perfect, just close.
Take your matt and crunch it up in your hands to make it more pliable. Cut the matting into 3/4" strips. Take these strips, and take a thumb full at a time and tear them into little squares. I fill a box full before I start glassing. When you lay your glass, try to not overlay on top of the tape too much, it will save you a lot of sanding time, and your repair will turn out much nicer.
Now you know how much work I have put into my body. Imagine trying to do 4 flares almost entirely out of glass - not easy!

Hi, so after you put down the glass over the repair you sand it with what grit of sandpaper? I see before and after picture but no one ever seem to state how they got there. Do you sand down to the tape then remove the tape snd continue with the same grit or finer?
Thanks,
Danny

I have 50 grit on a 7" grinder which I use to knock off the top layer... Pretty careful with speed control... Then I switch to 4.5" grinder with a 120 grit flapper disc... Use this down to the tape... Again, very careful with speed control... I then use 80 grit on a block (I have a 5 inch and 16 inch block)...
Won't use anything finer on my grits until I finish my last layer of filler...
