hiya,

I'm trying to make my own fibreglass interior middle panel thingy, the radio stuff.

The idea is to use plaster to mould the interior panel from the inside, then do a reverse mould. and add some custom bits into the plaster.

Get fibreglass resin and voila..

the problem is, I have no idea how fibreglass works...I have seen those fibreglass pack thingy sold in bunning, do I get one of these and it'll work? or do i need like a seperate resin to stuck everything together?

I intend to make a sort of "sliding panel" to hide my head unit, so the fibreglass section have to be thin. From what I have read so far, I need to sand the fibreglass to get smooth surface. but if my fibreglass is thin, I think it'll crack the moment I sand it... can I just spray a really thick layer of primer making everything smooth?

How do i get the super glossy look the audio shops produce when painting the panels?

cheers

make the panel with 2-3 layers of fibreglass if you want it to be extra strong, mix up the resin itself and brush it over the finished product - then you can prime it up etc make it smooth & ready for painting.

the fibreglass repair kits they sell @ bunnings would be sufficient,

either that or look up your yellow pages and find a shop that sells firbeglassing and moulding stuff, they will be able to help you out with supplying a proper fine weave glass (the bunnings kit's I have seen are only chopmat). Using a fine weave glass over chopmat will give you a better result with 'sharper edges' especially as it's only a small component.

To make the mould don't worry about making the inside mould just make the reverse one with the insert to begin with, polish the insert up with some floor polish so that it doesn't stick to the plaster mould. Then when laying the glass polish the inside of the mould with the same stuff so the resin doesn't stick to it.

For best finnishing results either do a gelcoat layer (this is easy and you dun have to mess around with sanding and painting and shit) the gelcoat layer just gets painted in before you lay the glass. The way they get the really shinny finnish is they use a 2pac paint and gloss out of a gun. Because it's an interior panel just bog it up with carbog to smooth it out and get a good surface for painting.

The sliding panel is a bit beyond me though, if I was gonna do that I would just use a plastic piece and paint it the same and find some plastic U channel for it to slide on and use some glass and resin to fix it into the back of the insert, as for keeping it open perhaps a small magnet or something.....

Heres my custom dash, is this what you mean?

I cut out a piece of arcylic to suit with a jig made for my router, then glasses it in from behind. Unless your good with a router I would nt reccomend it.

I used to design and build fibreglass body kits. If you need help on mould making and replication using gelcoat and fibreglass i will be happy to help. Its tricky if youve never done it b4 but once you know how its all pretty much the same technique.

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.

      Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.

      Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:

      Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
