    While i have been hanging around, i have been reading up on Jim's suspension upgrade, Marks v12 conversion and some other cool threads.

    Not much has been happening with my other projects so i figured what the h*ll, let start a new adventure. :)

    So any, my auto body guy came up for a visit today to check on this little rust problem i have. When i had pulled the muffler/cats package out i found some rust that had me worried. Check out the pictures.

    He told me it doesn't look like the frame but more of a cover/wrapping with plenty of insulation. (asbestos??)

    He told me to start taking out some stuff, so we can see what's in there, and he'll come up next week to take some measurements.


    Geez, did i just open a can off worms?? I knew i should have just wrapped it up with duct tape and walked away? lol

    Chris,

    It is a can of worms but it can be done. Take a look at my thread, especially around page three. I can send you more pics too if you want. The trunk is really about 8 seperate pieces of sheetmetal all tied in togther. If the small boxed sections that you see underneath are rusted badly you can almost count on the rest of it being bad too. At first I thought it was just those pieces but the more you take off the more rust you'll see. If you take off that center stainless heat shield you'll have a better idea what the rest looks like.

    It's really not that much work but it is time consuming. The insulation is raw rock wool. If you need info on what to replace it with I found some ceramic insulation that worked well and wasn't too spendy.

    Let me know if you need more info or any advice.

    John

    Here's the thread I talked about above...http://ferrarichat.com/forum/showthread.php?t=83679

    Newman's thread has a good series of pics too as restored his to the Euro style construction, losing about half of the pieces!

    As noted it's the insulation holding the moisture, then off you go......

    You're exactly correct. When I put the new pieces together I made sure all the joints were sealed well with high temp sealant and then painted over that with POR 15 and then high temp paint over the top of that. The rest of my car will fall apart before the trunk rusts out again!! It's hard to believe that the original design has as many gaps as it does. They just tack welded the pieces in and called it good. Lot's of joints for water to get in there and soak into the spongy rock wool.

    Chris, it really doesn't look like it will be that big of a deal to fix....

    Only if you still have cats, otherwise just remove all the extra sheet metal and clean up the frame, that is what I did. I also lowered the trunk floor. There are pictures on my homepage but they are similar to Newmans'.

    I think there are much better heat shield materials these days...check out Summit Racing....

    Dr Barry put something there over his ANSA that was even a Ferrari material!

    Stop short of the gold plating foil, used in the McClaren F1 engine compartment!

    Your center pan looks surprisingly good. Have you checked the pans out in the wheel wells yet? Mine didn't look too bad until I started poking at them. That's when I realized it was the rust holding them together! I can get you in contact with the company I bought my insulation from. I can't seem to find the part number but they should be able to figure it out. If you are putting the exhaust back in stock configuration I'd put the insulation back in there too.

    That all looks familiar for some reason, well except the digplex boxes or whatever that is in the drivers wheel well.

    It's really not as bad as it looks though. I probably spent more time trying to figure out how to get it all apart. The wheel wells are just riveted in. The boxed sections under the frame are tacked in, and not in convenient spots to get a grinder in either. Once you get all insulation out it's a lot easier to see it all.

    Wait till you get the insulation out and see all the rot from above. The shock mounts and all that extra crap in there that just adds weight and makes rust.

    Chris,

    As Bubba mentioned, My ANSA Sport muffler had burned a 2 inch hole in the fiberglass trunk panel above it, exposing the rock wool insulation. I attached the heat reflective/insulating material used in F40 engine bays to the fiberglass panel as pictured below.

    Thanks for the picture Barry.

    Here's a update. I got most of the rock wool out, and i also took out the digiplex. Looks like i have to cut out that middle panel and replace it with..........galvenized or SS?? Maybe?

    Yep, it looks like it is shot. The center section was also tack welded under the cross support on mine. I was lucky on that pan, Newman had one that he didn't use so I grabbed it. If you have a sheetmetal shop anywhere close by it would be a simple piece to make. Steel would work just fine as long as you paint it. I used galvanized for the two small pans underneath as they seem to see the most water but the rest I just used mild steel.

    Yeah, i called Gloria and ask her if she had 48"x60 or anything close to that, but all she had was 60"x225. Big rolls :eek:

    She told me to try Mcmaster. So i'll try them and see what they have to say.

    Chris rip that stuff back out and go euro in the rear. You dont have to change the tail section or rails just get the shielding out of there and leave the rails exposed. You dont need all that sheet metal in there and in the end it wont look very good. Sorry its just my view on it.

    You know Paul, i was debating on if i should leave it out. I wasn't sure if the shielding was there for a purpose (protect the rails or something else??)
