What is the best way to join two different plastic bars together?
I want to endevour on a bodykit making mission. I saw EFFalcon's ride and what he has done and it inspired me to have a go. I talked to him about joining the two bumpers and he said that he used pop rivets to join the two. Was wondering what other methods would be good in relation to flexibility and cracking? Fibreglass over the joins perhaps? Anyone got any ideas or had a go at doing this? Would be interested in your thoughts. Cheers, Tim

Pop rivet and sicaflex underneath to bond it well and truly then fibreglass and bog to get if filled and smooth.
My rear bar is a 3/4 section to the EA rear bar, it was stock on with sickaflex, I then fibreglassed it and filled ot be one big bumper. Only a small pic off it, but its been like that for over a year no cracks or anything.

when i did my EF bumper i just used a $20 80 watt soldering iron and heaps of scrap plastic as filler, then fiberglassed the back, it has only cracked in a couple of plces where i didnt fill it enough.

my old job was plastic welding ,you can weld them together but has to stay cool on the other side to stop the plastic warping and just spot weld in small sections, sikaflex is good drill and countersink the holes put rivets in , put a small amount of fibreglass over the join then body a weak mix of bodyfiller, if the body filler is mixed wrong it gets to hot and will warp the plastic .

fibreglass works fine, though seems to crack fairly easy when bonding to plastic, this is only if its actually holding most of the force.
plastic welding is a good way if u know someone who can do it, though each bumper is made from different plastic so it *might* matter. there is also a special type of glue that can be used, but i'm not sure what its called. i went for something to force them together then to just rely on something to 'stick' to them.

By the sounds the pop rivets may be the go....counter sunk to stop any bumps.
Hey EFFalcon....when you did your bar did the pop rivets go underneath the mould so that they wouldn't be seen? Cheers, Tim

Yeah, i didnt counter sink mine as they pulled themselves in anyway, they're only real thin.
then i put the black mould strips back over the top to hide it all. fibreglass used elsewhere to smooth it out and hide rivets.

you can use a heat gun as a plastic welder just but the small tip.there,s another to help with flex its called SEM its a rubber repair kit for bars like hsv,s and au xr stuff .

i used fibre glass on mine i used it on the front side of the bar and rear then used body filler ( the stuff with the fibreglass strans in it then fine body filler it works fine didnt crack and is real solid i would have prafered to plastic weld but it just was readly available and rivets would have shown though on mine cause the front has been smoothed
heres pics http://i11.photobucket.com/albums/a152/ ... 0_9503.jpg http://i11.photobucket.com/albums/a152/ ... 821e65.jpg in this pic you can see there would be no where to hide the rivets http://i11.photobucket.com/albums/a152/ ... 0_9506.jpg |

Alternatively ring a few places like 'dash repair' and so on guys as they do plastic welding quite cheap.
to get a whole bar plastic welded some guy in syd quoted me only $150 .. cheap considering all i had to do was have the bar off! loctite psychoglue with fibreglass is great i might add, quickrepair to mine LOL

Good to hear that there are a few different options available...
Guess it will be trial and error! Tim
