    Undercoating Removal

    in Body Kits & Paint

    Posted

    Thanks for all the tips Sam. I'm glad the reducer is working for you. It's all those nooks and crannies that were killing me as well.

     

    I played around with quite a few methods myself, but I never tried oven cleaner. Might have to give it a try on my spare tire well. The stuff on there has a coat of white paint or primer on it and it seems harder than the rest.

     

    Thanks again and good luck with yours.

    Thanks for the kind words guys. The reason I am getting it so clean is because I am not going back with undercoating. Going to go either the truck bedliner route or chip guard with a urethane paint. The guy who sold me the car is a painter and also a good friend. He wants to do the chip guard but I am not sold on having a paint finish under the car. I'm sure it would look sharp at first but I don't think it would hold up.

     

    After all of this I am probably still going to sandblast the entire bottom of the car. The more I think about it I don't think I want to reuse a primer that has been covered with a petroleum based product for 28 years.

     

    Thanks again and any opinions on what to coat the bottom of the car with are welcome.

    I'm curious about the color of your underbody. When I removed the underbody coating, what I have left is bare metal. Yours looks like it's coated with something, like paint. Was there a paint layer under your underbody coating?
    There is a layer of paint or primer there beneath the undercoating. My 72 240 that I started with did not have the paint, it was just bare steel. I gave up on the 240 just too much rust.

    Out of curiosity, at the bottom of the second picture I see a dark line running left to right along the box section of the door sill, touching the seatbelt pocket. Is that absent metal?
    No that is a stripe of black paint. Looks like somebody painted the wheel wells and the area below the rocker at some point.

    I know we have touched on this before but I wanted to share my experience on this so far. Had a pretty good weekend and got a fair amount of the car completed. Here is a pic of what she looks like naked :D

    My rust free body shell ended up having a couple of rust through spots that I didn't find until I removed the undercoating. This was the reason for going through this process in the first place. Here is the worst rust I found, minor but still needs to be repaired.

    The process I have been using to strip the undercoating goes something like this.

     

    1. Saturate an area with carb cleaner and let it soak in a minute. Start attacking the heavy stuff using a stiff scraper and reapply the carb cleaner as needed. I have used a combination of tools thus far including a stiff scraper, putty knife, stiff plastic bondo applicator and an assortment of wire brushes.

     

    2. Once you have gotten all the heavy stuff off you can attack the lighter coating that is left with a spray bottle full of acrylic enamel reducer and a scotch brite pad. You will create a thin coating that can be wiped clean with disposable paper rags. I bought the kind that dispenses out of a box. The enamel reducer works great and you can buy it in a five gallon drum inexpensively. I bought mine from the local Keystone Automotive distributor. I believe they have something like 150 locations nationwide. The enamel reducer evaporates quickly and can therefore be applied heavily in tight spots to literally wash the undercoating away.

     

    3. You can spray one final application of the enamel reducer and wipe clean, then you are done. You can either sand the surface or go with a light sandblasting if you prefer.

     

    I used a layer of visqueen topped with a layer of 15# roofing felt to protect my garage floor. This is a very messy job and always wear quality gloves and eye protection as you are doing this.

     

    Just thought I would share my experiences thus far and I am sure there are many other methods to accomplish the same end result.

    Not sure about that company, but that style of device has been discussed. It looks very useful if you are not going to fully disassemble the car. A rotisserie is the way to go if you are taking it to a bare body shell. You can check out the plans I used to build mine here If you do a search in the paint & body section under rotisserie you will come up with a welath of information.

    When I went and looked at the car the guy indicated it had an electric fuel pump so that is what you are hearing. You could verify this easily by turning on the ignition and the see if the noise quits when you flip the switch under the ashtray lid to the off position.

    What else should I remove?

    Before you remove the power steering pump I would suggest you remove the belt and take it for a test drive. A disabled power steering acts nothing like manual steering it takes way more effort. Most cars are near undriveable without the pump working. To each his own on the A/C but I'm in Florida and can't live without it.

    Scottie,

    I think I know the car as well, makes me glad I didn't go to the track Friday night, just too depressing.

     

    Mike,

    Be careful out there nono.gif

     

    The only way I know to hold the valves in place is with compressed air. I don't have a valve spring compressor but I'm sure you can rent one if all other sources fail. Since you don't want to pull the head I'm assuming you already put the 2mm gasket on. You certainly should be getting proficient at it by now twak.gif
