I have a damaged 944S2 batwing, torn and a protective undertray with missing tabs.
*Does anyone know what material this is made of? I'd like to plastic weld or otherwise repair it, but cannot work out what the material is.

951and944S

Pretty sure the batwing is urethane, I never kept them around long enough to damage one, replaced all I have owned with the GT Racing splitter.

Never was much on "Bondo" brand items outside of spreaders/consumables but this product works really well - http://www.oreillyauto.com/site/c/de...2545&ppt=C0171

The bottom tray has fiber impregnated so it's more than likely "SMC". Means "sheet moulding compound", fibers plus polyester resin pressed into a given shape, so polyester resin and fiberglass cloth (random strand mat to replicate factory) would be the preferred method.

Epoxy resin is always my choice on a scratch part but there is an uneven molecular structure difference between epoxy and polyester resin and it's not recommended to mix products.

i would bet with near-certainty it's ABS plastic.
you might find a cast-in mark somewhere that denotes the type of plastic used - PP, PE, ABS, PU, etc.
maybe i'll take a look at mine later today to verify.


if it is ABS you can use regular black-plastic-plumbing-pipe solvent glue.

Solved it. The old panel had no markings (944.504.167.00), but a new one does (944.504.167.01)

>PP-GM 30<

The local Porsche parts guys got it in from their warehouse so I could take a look at it, we didn't know if it would have markings either, but it does. I've become well acquainted with them over the years, good guys.

Mind you, I don't know what the -GM 30 means.

PP = Polypropylene.

quick google suggests it's polypropylene with fiberglass reinforcement mixed into the plastic during casting for strength.

I had done a Google search, but with clearly not as good a search string V2Rocket, as yours.

I improved my search query and found that GM is Glass/Mica and 30% is the percentage of Glass/Mica in the product. (I hope that's correct, anyway it allows me to confidently repair my old one)

I was even considering Drifter's Lacing to repair a tear, but drilling holes in things doesn't seem right.

Much appreciated, thanks to all of you.

is that "drilling holes and stitching with zip ties"?

coonabarabran

Yes, exactly, holes, zip ties in a cross stitch pattern, but I have seen smaller stitches in parallel rather than crossing.
