    Liquid plexiglas is a liquid acrylic that you can pour and sets up clear, plus it doesn't need any strengthening material like the fiberglass mat. The reason we use fiberglass with epoxy is that the resin doesn't cure stable, it cracks very easy and only has strength in thick blocks.
    Also, MEK methyl ethyl ketone is polyester resin hardener. You can find it at any marine supply shop, along with fiberglass stores and plastic depot, like TAP plastics.
    They will also have acrylic sheets and acrylic bonding solvents at TAP, and most of the pourable plastics.

    The main reason people use fiberglass and bondo is because they don't pour, they spread. It's very difficult to make a reverse mold that you can FILL with an acrylic or ABS formula where it will come out smooth. It's much easier to sand bondo. That said, you can come up with some cool results using the acrylics.
    I've used all of these methods extensively, and if anyone needs help with them, please ask.

    It's right in the middle of what you quoted. TAP Plastics. And if you want a lot of the liquid acrylic, they sell it at select products.

    So your using PVC pipe??? or do they make an ABS pipe? I guess it's the same? dunno..

    That Oatey ABS cement looks slick.. you'll have to post your results with that too...

    Do you think that you could accelerate the drying of the sludge by using heat?

    And for creating shavings, you could use a rasp type file which u could shave the pipe with...

    And for breathing protection, I get 3M throw-away respirators for $16 bucks that work awesome...
    They are good for about 8~10 hours of organic fumes if not a little longer.. and then come in handy for dust after that.

    The white or gray pipe is PVC... ABS pipe is the black stuff... I guess they would both work but if I ever get a scratch in the paint finish of my dash, I'll have a black scratch not a white or gray one...

    I need to go hit the hardware store to get some bits for my dremel... I'll need to smooth out a few areas, and then build things up in a couple others... I'll try to get some work done tonight and maybe get some pictures posted up tonight or over the weekend... I'll check back in a bit... later!

    I meant to reply to your comment... just for the record, the final product will look no different whether you use the old bondo and glass method or do the plastic... the difference is that most likely if not definitely, the glass and bondo will crack... the plastic won't... as long as your prep work is meticulous... anyway, once I'm done with the sanding and stuff... the paint (if I do it) may not be GREAT as I suck (or at least HATE) painting... lol

    Later!

    This is where I have purchased all my acrylic stuff. http://www.ipscorp.com/ind_html/indprdcts.html
    I have used the solvent and it is very strong. Some people will take acrylic chips and the solvent and mix them to make a cement, or you can purchase it in a tube. The problem with this is that the dash and the monitor case are not acrylic. So they may stick but they will not bond. I believe it's more like PP (polypropylene) or PE (ABS/polyethylene), which can actually be welded with heat, but can not be bonded my disolving the material then letting it harden again. You can glue it with some high strength epoxy though. So for the dissimilar materials I think structurally fixing the pieces with epoxy then finishing in either fiberglass (for high fill areas) or bondo (for low fill areas) would be the best method.
    Another good source of info on this plastic stuff is http://www.eng-tips.com/threadforum.cfm?lev3=80

    They do make abs pipe. As said, it is the black pipe (not the iron black pipe LOL) at home depot. The difference is that abs (PE or polyethylene) is a thermoplastic meaning it can be melted and therefore, welded to itself. PVC is a thermoset. It can not be melted and used for anything useful except a big stinking glob of melted, burnt dog **** and maybe to get high.
