Does anyone know what the coating is inside the trunk? Its on the floor, wheel well, and quarters. It looks like a spray-on undercoating, but its not sticky and is not soft like undercoating.

I assume (but don't really know) its original because you can chip it off and there is clean metal underneath.



Is there a spray bomb product like undercoating that dries hard and would be OK in a trunk?



Any suggestions/recomendations?

    3M makes two spray-on undercoatings, one a little more "rubbery" than the other. I used the less rubbery material (3M No. 08881) in my trunk. Put it in on top of POR-15 when it was still tacky. It seems to hold well enough to the latter, though cured POR 15 is slick and requires a binder primer to paint. Also used same undercoating to come up on the inner fender wells, etc.,as was done originally. Looks good. Gets reasonably hard, and IMHO looks pretty much like the original material.



    You need to use with good ventillation. It seems to have a very volatile solvent. One pound can runs $8 something at NAPA here. I used the better part of two cans to finish trunk. Have not tried the other type. It is bit more expensive. Can google 3M for more info. on product.

    I don't know where you live, 48super6, but if its anywhere near heat.........don't use undercoating, or at least similar stuff to the original. My Pacemaker is parked here in AZ and all the undercoating in the trunk and fenderwell areas is softening and sticky, like glue. Gets on your fingers and is a bear to get off!

    Don't know what I'll use yet, but going to check with the locals guys here to see what stands up to this heat.

    There is a product called "Gator Guard" which is an epoxy-based sprayable truck bedliner. I have used this to replicate factory undercoating and it works very well. It does not get soft in the heat like the asphalt-based aerosol products and will last practically forever if the surface is sound and properly prepped. I think it would work well for a stepdown trunk.



    You will need a "shutz" type undercoating gun to spray it, so it is a little more work, but well worth the effort. The last time I looked, Eastwood carried it. I like the epoxy base because you can spray it with a standard respirator. There are urethane-based bedliners that are good products, but they contain isocyanates like urethane clear coats and I try to keep my exposure to isocyanates to a minimum.

    Hey Rick,
    I have used Herculiner. It is great. I used it under the fenders of my street rod to prevent "stars" from rocks in my expensive paint job. It works. As a side note, if you like a smoother look instead of the sandy/grainy look don't stir in the grit stuff that is at the bottom of the can. It is there for non-skid applications.
    WARNING: It sticks to everything. If you get it on your clothes you might as well throw them away. If on your skin, clean with thinner or it will be with you for a couple of days. How do I know? Been there, done that!
    Peace,
    Chaz

    I'm not sure where I read it, but I do remember that a component of the original product which Hudson used was silica. You might try reading My Years at Hudson by B.J. Siegfried.

    I found Dupli-color and 3M both make pick up bed liner in spray cans and its available at NAPA and Walmart. I picked up a couple of cans and tried it. It goes on a lot smoother and thinner than the original coating. If you spray on multiple coats and keep them kind of "dry" you can build up a little more texture. It seems to work pretty well.



    Thanks to everyone for your replies.
