You ever read something on another forum and you just....

I saw someone recommend an fd3 rx7 in response to someone asking for a recommendation on a reliable daily driver once...

working at tha zone I heard a lot of crazy stuff, we had one guy that worked there that thought the engine gets hotter when the thermostat opens because "the water moves too fast through the block, so the thermostat closes to make the water cool the motor down, then opens again"

Direct Exhaust Injection...

That one's an all-time classic.

I don't think anything will ever top that one. Not even the "Welded Diff". 

I like to think that DEI is trolling, but I work in a world of engineers.  In public design competitions or even internal one, there is always someone that presents an idea that involves generating 'free' energy, but violates some law of energy conservation.

Back in the day when I was not very confident about residential electric work, I asked a forum for advice on something.  This was a forum for electricians.

I forget what my question was, but one of the answers I got was "as long as you have enough wattage coming out of the wall outlet..."

Ow!  that one stings.

He says that he was trained in the military. I wonder if the no sanding thing was more to prevent stressed aircraft skins from getting too thin after being repainted every few years. They're trying to make the B52s last 80 years. Imagine how many times they get repainted and then think about some jackass trying to sand out every little scratch every time they were painted.

Probably.  Different areas of the aircraft skin/structure have different limitations as to what can be blended out by sanding, what needs to be cut out, and what needs to be removed and replaced. 

Also, on aircraft skin there exists a pure aluminum clad (Alclad) layer that is there to prevent corrosion.  Disturbing it could have consequences that may need to be taken into consideration for certain areas. 

His post tells me he grabbed one set of restrictive repair instructions, completely missed how and why the limitations were applied, and just completely ran with it.

Something about Jag V12s

Funny thing is, my first reaction before I read the thread was "did you somehow end up on a certain Miata forum?"

Could have fooled me with club 4AGE

Every Jeep forum...

There's this thing called Twitter, maybe you've heard of it.

He had me till $10,000 to polish Vette rims. Lololololo lo lolzers.

No, I think he polishes $10,000 rims, not charges $10,000 to polish them.

 

But it's a one of 3 rare 1987 automatic Corvettes, with 1,708 original miles, so maybe not.

Sooo, there does appear to be some truth to what that guy was saying...

 

For example, if you scratch ss while working on it, it can rust.  Also, you can decarborize steel alloys by exposing the underlying surface. 

 

These 2 points are both WAY down the rabbit hole and not really applicable to what we are doing here.  However, in the steel manufacturing industry, they are concerns (as well as some others).

 

Usually, heat (and atmosphere) is more likely to mung up the material more so than physical manipulation...

Okay, here we go- Can stainless steel rust if you sand it- yes. It's not due to the scratches though. It's due to some knob using the same disc/paper/sanding stuff that he used on mild steel. The particles of mild steel in the flap disc/sandpaper/wire wheel will transfer and contaminate the stainless. That's a big no-no when welding food grade stuff...

Decarburizing is a result of too much heat, iirc. Has to do with the carbon migrating to weird places. Stainless is even worse. The metals that make stainless "stainless" are chiefly nickel and chromium, depending on the alloy. If you overheat the weld, those go away and you're left with dark gray or black metal that is brittle, won't weld, and rusts. Welders call it sugar, and it's a bad thing.

Yay, rabbit holes!!!

Returning to the original question, I bought a WRX this spring.

Need I say more?

I'm looking at Impreza hatchbacks more than is probably healthy...

LOLzers, I thought the same thing.
