I have no pro stuff, so I won't be using it for its intended application. From the research I have done, this appears to be some pretty decent stuff.....not smelly or a PITA to work with either.

    Thanks for the link - I watched that and it looks good if I ever have a big job to do.

    The paint-able stuff will be a bit different, but it is still just rubberized undercoating. If you scrape it with your nail, and it is warm out, or if it has been in the sun, it will come away gummy. Try it on a scrap piece of MDF...wait a couple days and paint it, just to see...Then if it feels ok to you, by all means use it.
    Yes! I've only used it once maybe 20 years ago and I do remember that if you scraped it with your nail it came off, lol! I did plan to test it and the Duplicolor Truck bed stuff. Thanks again for your input.

    No need for a pic unless you really want to, if you say it looks the same that's fine. I got the similar paintable product so, I'll just try it. Thanks again.

    I think it's the same stuff but I couldn't get an answer either. It leaves a nice dark texture. I don't have any pics that show the detail up close and I am stuck at work all weekend. If I get a chance I'll upload a close up pic for you later.

    Thanks Blank, did you get the same texture/color as WWWJD, do you think that is what he used?

    I used the unpaintable 8881. It stinks for a while and takes a long time to completely dry. I would assume that the undercoat that you can paint would dry or it wouldn't work very well.

Go with the spray on truck liner...same look, hard as a rock...paint it if you like.
    Thanks for commenting, your points are why I asked it just didn't seem right to use undercoat. Do you think the formulations have changed so that they fully dry these days, for lower VOC and all that?

    Do you think he was thinking truck liner when he said undercoat? 3M has an undercoat product that can be painted and I just bought that one to try but I'd rather rule it out and not waste the time if it is not the right thing. The pro auto paint shop that I went to had the 8882, and 8883 and the regular auto parts store had other 3M undercoat products .... so many to choose from.

    Here is a comparison of truck bed liners, etc. and he does seem to prefer the Duplicolor products. The black truck bed liner is not that deep of a black and he then paints over it which is something I might want to do:

    The 3M product is undercoat not truck bed liner and comes in low VOC (8881), and paintable (8882). I might just try the paintable and then see how it looks with a deeper black over it.

We have an excellent automotive paint supply store nearby, I might just print out the picture and ask them.

    Also wondering if it can go right over the edge grain on MDF since it is textured.
    I'd look at either plasti-dip spray (available at home depot), or duplicolor bumper coating or spray in bedliner

    Duratex is as close to simple and bullet proof as you can get. I use the cheap white foam rollers, but you can use any roller you want and get more or less texture. I left a Duratexted MDF scrap out in the sun, took over a year to delaminate. It can be sprayed with a texture gun for drywall.

    Leland sells the black in pints if you want to experiment. http://www.speakerhardware.com/categories.php?cat=10

    The factory also sells white that can be tinted with water soluble dyes and pigments. http://store.acrytech.com/Speaker-Cabinet-Coatings/

    Here's a couple Duratex cabinets:
