Personally id would get it done by a plastic welder brad mite cost a bit but should be like knew after wards

[dattoman]

Go see the local panel shop and see if they have access to a plastic welder

 

If not just hang it on the wall and buy a fibreglass replacement

Hi Brad,

I've heard of the old soldering iron and cable ties melted into the crack.  Check "YourTube" for other ideas.

Try a bumper bar repairer or a bike restorer.

Not sure what plastic the SLR rear spoiler is made of but ABS (Acrylonitrile Butadiene Styrene) is commonly used to make plastic panels for cars. It is easily welded with a reasonable sized soldering iron and some scrap pieces of ABS to use as filler.

 

If your not confident about doing it yourself then take it to a professional to be repaired.

Yeah, Methyl Etheyl Ketone (plumbers Pvc priming fluid) will do the same thing, however I think welding with a soldering iron or hot air welder would be 10 times quicker and stronger.

They are ABS and they can be plastic welded. I've had them done before, a decent repairer will do a good job. If you wre in Sydney I could recommend someone but try a bike fairing repairer.

There used to be a good bumper/headlight place at seven hills, just over the bridge there, not sure if they are still there now tho sorry.

I could weld it for you for free with the oxy, but I won't guarantee it will look the same when I'm finished.

Get someone who knows how to do it might cost a little extra but will save you in the long run. Welding plastic together with a soldering iron is really only good for small things, even then its dubious if it will hold properly, the soldering iron heat upsets all of the resins in the plastic making it difficult to get a real decent bond.

[71xu1]

Not 100% sure but from memory the resin does not adhere too well to the plastic. Best of plastic welding it works 100%

I'm guessing that Brad is trying to fix it himself as the nearest plastic welding expert is hundreds of miles south????

 

I was going to suggest you post a pic to show everyone how big your crack is that needs filling but then I realised that sounds like a strange perverted request so I won't suggest it.

I used a company called plasti weld in Bankstown years ago, they did bike fairings.

If you are looking at repairing this yourself, DON'T use fibreglass or resin. I have seen plenty butchered this way. You can buy a plastic filler which is like bog which is a much better option. I did have a contact I bought mine through, I'd have to look back but you can find places on the net.

The best way to do it is buy a proper welding gun, I have one but they are around 6-700 bucks.You can use a soldering iron as well and buy yourself the proper ABS rods to melt into the plastic gap. Another option is the little butanne heat guns you can buy from places like bunnings. When you use them, only use them to blow heat, not a flame. ABS requires around 300degrees to melt.

There are also mobile guys who do this work like the touchupguys. One of the guys here in Sydney is a Torana man and has a touchupguys frachise. In the case of a dash and the grain they make a mold first of the pattern and melt that back into the repair so you can't see it.

^ that's fantastic news for some.

I have two original plastic rear SLR5000 spoilers to repair and was also wondering what to use to fix them. While at Sema last year I saw a demonstration of a plastic repair using a product called Plastex. It looks the goods and comes with a instructional video and I will using it to do my plastic repairs. Here's the link:

Brad there is a mob down this way called 2K Plastics

 

I have asked Kipper the owner about this before regarding rear spoilers as i have the original one off the car as well that is cracked near the keyhole

He said he would need to take a look

 

Havn't got round to digging it out as it is 2 stories up in a sea container ATM

 

Not sure on a price but i'm sure he would look after you

I repaired a cracked plastic case on my laptop with a 35W soldering iron. It is now dust and water proof, but it doesn't look very pretty. With a bit more time I could improve the look, but you can't see it when it's sitting on my lap. Most bumper bar/ headlight repair places do repairs to a time limit. Keep that in mind.
