    Best product to secure LCD frame to bezel?

    Hey guys....thinking of trying my hand at all of this. I have a lot of experience with fiberglass and bodywork (see Big fiberglass project). My question is what is the recommended product to attach the plastic LCD frame to the plastic bezel? Before everyone says "search"...I have. I notice that Dynatron seems to be a popular solution. I have also noticed that Nexson appears to use Mohawk instant glue. I have read all the popular "how tos" etc; however most of those posts are a couple years old. I was just wondering what the "goto" product was for this scenario? Any help would be greatly appreciated.

    A lot of it depends on the materials being joined. The worst-case scenario is when one of the parts is polyethylene or polypropylene, because these are very difficult to "glue" to anything else. The best case is probably when both parts are ABS, which is easy to join with any of several ABS bonding agents, most of which "melt" the ABS parts together.

    The best advice is to take an educated guess at the best material to use, and then try it on a sample.

    Check the Urethane Supply site; there's a wealth of information there on plastic joining, and on ways to identify the materials you have.

    Thanks RDholtz! I saw the obstacles you had to overcome with your project. In my situation I have a Lilliput LCD frame and a GM plastic (I'm assuming ABS) radio bezel that I would like to join. The dynatron is an epoxy based product, right? And then the CA glue is basically "superglue"? I understand your suggestion at guessing and trying different products, but I was hoping someone could make some initial suggestions so I didn't have to order/buy numerous products and try them to figure it out. I would hope enough experts on here have already been through the headaches in most of these scenarios. Once again, thanks for your help! Any additional suggestions would be greatly appreciated!!

    You want to permanently bond the TFT panel (including touchscreen overlay) to your bezel? That's probably not such a great idea if you ever want to replace the touchscreen overlay or panel. The way I did my screen install is to just use the existing lilliput bezel which has 4 little metal tabs that screw onto the bezel and hold the LCD in place. Then I did my fabrication/cutting around the existing bezel.

    When I did my GM truck and my Scion I used a product called "plastic epoxy". It is a 2 part product like regular epoxy but it also "melts" the 2 items together. The scion was done a couple of years ago and the truck about a year and a half with no issues at all. I used body filler after the epoxy dried and I shaped it correctly. Then automotive base and clear coat finish.

    I'm sorry, I should have been more clear. I don't want to permanately bond the actual panel to the bezel. I meant the LCD screen plastic housing to my bezel as is the common practice on these forums. Sorry for the confusion!

    Oh, ok, in that case, you could always just cut the LCD bezel/dash piece such that they roughly fit together then reinforce it structurally with epoxy, jb weld, or abs plastic (melt it with acetone). Then cover the holes and gaps with bondo and sand it down, then paint.

    hey, So Eric, I will be talking to you a bit on the phone later, to explain this. In the mean time, I am going to put together a little DIY of the products I use for bezels, hopefully it can get stuck, so that everyone can see how I do it.

    Hah! I would VERY much enjoy a DIY for other products (rage, duraglas, fiberglass/resin, etc), as I am about to embark on my first use of fiberglassing products. This painting video was definitely of use as well.

    Sometimes there are manufacturing marks molded into backs of the parts, and they're coded to tell you the materials. They'll say "ABS" or "PE" or "PP + (some other plastic)", for instance. Once you've determined what materials you want to bond, I'll bet you'll get some guidance from the experiences of others.
