big boo boo happend to my car today :)( ...am devastated.

was going down a basement carpark ramp and scraped slightly on the undercarriage.

then on the way out ...i attempted the same ramp at an angle...got stuck and the rear wheels started to spin and I could hear this god awful scrape and thud.

being the idiot i am..managed to get the car in reverse and attempted the ramp again ....same deal...even tried it with some drain grills which i removed and made a platform to jack the rear a bit...car was too heavy and the steel grills didnt hold.

anyway short story....i scraped my undercarriage and the tar like stuff was scraped exposing some bare metal...also bent the metal cover on the cat. thankfully it didnt dent the chassis or any other body parts

my q is.....what is that tar like stuff on the chassis and where can i get some??? is it sold in a spray can or can i brush apply the stuff??

am really worried that the metal might rust if i leave it exposed too long.

sorry guys...i know it sounds lame...but i really like to keep my car in immac cond.

sound proofing ....the RAC guy said it prolly was rust guard and since i work at the beach didnt want the undercarriage rusting. anyway thanks for the advice Paul I'll go to repcos 2morrow and get the stuff.

    • It is an absolute lottery. They can and have died at stock boost with low usage at all. The turbos are now anywhere up to 36 years old!
    • Huh, wonder why it blew then. I never really beat on the car THAT hard lol I dailyed it and the turbo blew after 6 months
    • That's odd, it works fine here. Try loading it on a different device or browser? It's Jack Phillips JDM, a Skyline wrecker in Victoria. Not the cheapest, but I have found them helpful to find obscure parts in AU. https://jpjdm.com/shop/index.php
    • Yeah. I second all of the above. The only way to see that sort of voltage is if something is generating it as a side effect of being f**ked up. The other thing you could do would be to put a load onto that 30V terminal, something like a brakelamp globe. See if it pulls the voltage away comepletely or if some or all of it stays there while loaded. Will give you something of an idea about how much danger it could cause.
    • I would say, you've got one hell of an underlying issue there. You're saying, coils were fully unplugged, and the fuse to that circuit was unplugged, and you measured 30v? Either something is giving you some WILD EMI, and that's an induced voltage, OR something is managing to backfeed, AND that something has problems. It could be something like the ECU if it takes power from there, and also gets power from another source IF there's an internal issue in the ECU. The way to check would be pull that fuse, unplug the coils, and then probe the ECU pins. However it could be something else doing it. Additionally, if it is something wired in, and that something is pulsing, IE a PWM circuit and it's an inductive load and doesnt have proper flyback protection, that would also do it. A possibility would be if you have something like a PWM fuel pump, it might be giving flyback voltages (dangerous to stuff!). I'd put the circuit back into its "broken" state, confirm the weird voltage is back, and then one by one unplug devices until that voltage disappears. That's a quick way to find an associated device. Otherwise I'd need to look at the wiring diagrams, and then understand any electrical mods done.   But you really should not be seeing the above issue, and really, it's indicating something is failing, and possibly why the fuse blew to begin with.
