Hello all. As you can tell I'm new to this forum. I have been doing car audio for about 6 yeras now and have tried my hand at tons of different projects. I can fiberglass like no other, but when it comes to making two plastic panels look like one, I suck! I will give you some background on what I'm trying to do so someone out there can give me some pointers. I currently have a 2000 Civic. I bought a X-Box and a Clarion 7" widescreen LCD. What I'm trying to do is put the LCD screen in the dash and make it look stock. I do not want it to look like it was just screwed down, I actually want the front shell of the monitor to be "welded" to the radio bezel so I then can paint it and have it look like a factory option. I have tried to make fiberglass stick to plastic in the past, but no matter how much i scuff, it doesn't stick when the part bends, and plus I do not have alot of room to really fiberglass, nor width (I don't want it sticking out really far. I heard there is like a Bondo type material, but for plastic bumpers. Someone told me it flexes, adheres to plastic, and you can sand it, but he forgot the name. Does anyone know?? Thanks for the help!!

We just started using a product called Duramix - the same stuff you use for repairing bumpers BUT a different model number. You use Duramix 40/40 for the cementing - doesn't sand very easy, then 40/58 for the final finishing as it sands much easier. It's a two part product and should be readily available in your area.

After final sanding, you can texture it or featherfill and prime for painting.

you can also use epoxy from West Marine systems to join plastic to plastic or fiberlass to plastic or wood to plastic, I have also used it brushed over the foam on dashes and such to bond things to it and strengthen it up. It is available at most paint and body supply shops or marine repair supply stores

If you can fiberglass like no other then you should make a custom bezel to hold the screen. You could then make everything how you want it, everything will match, and it could look stock.

Just an Idea.
