Bit of background...

My 34 has some nasty rust on the strut towers and the only way to clean it all out is to cut the top plate off and replace with a new one and obviously at the same time, protect the plate below by rust proofing it for the future...

I've already sourced new top plates from wreckers so now just need to take it to the panel shop to take out the old strut tower top plates (they will cut them out and pop the spot welds so that we don't have to remove the WHOLE top plate which goes under the front guards as the section towards guards isnt rusted).

Anyway, the new top plate will need to be welded on top of the strut tower. However before we do that I need to rust proof the bottom/main strut tower plate underneath so that rust doesn't come back. But since this is going to be tig/mig welded I'm thinking any rust proofing like Penetrol will melt away from the whole area once the welding starts due to the immense heat. And also obviously once the top plate has been welded on I can't rust proof any more as the bottom plate will be sealed off and inaccessible..(other than through tiny gaps UNDER the strut towers which are the source of the moisture .. friggin sandwich plates)

QUESTION:

Is there ANY rust preventing stuff out there like Penetrol that won't melt away/disappear from the protected surfaces if you weld nearby ???

      And that's a massive problem, because deadshits will deadshit and give you false details. At least in these days of mobile cameraphones, it is trivial to take photos of any ID they are carrying at the same time as the 300 photo extensive documentation of the state of the vehicles that I recommend even for minor incidents. And you get photos of the person's face, any visible tatoos, etc etc, while you're at it. Then you try to avoid mentioning that you're fully capable of making explosives of various power levels and will wreck their shit if you are forced to hunt them down.

      No, I don't remember the exact reasoning (was 20 years ago!) but the cops didn't end up supplying it to us either. Actually my mother went through a similar thing recently where she was hit when stationary, flustered and didn't get address (she got plate details, name, phone and insurance company, but not address). Person who hit her blocked her number and their insurance company (naturally) would not provide any details. Her insurance company also required her to pay the at fault premium because she did not have the address, cops did not help as it is a minor civil matter (they said their only course was if the other driver had left the scene of the accident without providing any details). She only ended up getting that refunded because they happened to be insured with Suncorp and she was with APIA so same company owners. For some reason the address is critical in insurance companies recovering money from the at fault party

      If you're driving something like an R32 through to R34, no chance of meeting Euro4. Euro4 came out in 2006, and car manufacturers back then were complaining how hard it would be to meet those regulations. Not a chance a vehicle 10 years earlier is going to be compliant.

      I presume it would take more than just slapping a big modern catalyst on the exhaust? It's interesting though, looking at the old sales brochures and listings it does not mention anything about emissions. No one cared.

      Yeh nice, looks like their part of keep it reet? Will have to swing past. I'd much prefer someone actually look at my car and custom make a part, then get a generic part online and hope it works.
