Diecast imperfections information

[randyc]

It is mentioned in another thread here about paint rash and metal rot or rash.  I understand this to possibly two different conditions.   Here is an article from george Bojaciuk on the metal condintion.

http://www.jsssoftware.com/pdf/diecast_rash.pdf   Apparently this came from MCM?  If you go up a level, you get this, http://www.jsssoftware.com/aspx/diecast_tips.aspx , which has a lot of tips on diecasts and some specific car repairs/adjustments that may help.

And maybe that little bit of paint rash may develop into a full blown rot condition where the metal actually crumbles.  I post it here because I had to go on a search for it myself.  At this point, many of us have cars that could be a couple decades old.   Or we may be buying cars that old.   You can often see how bad a rash is in the listing photos. 

When I do photos, I try to show it if is bad enough to look like it is affecting the car.   I have commonly seen rash affecting Ertl's 68 CHevelle SS396 in black, and the Danbury Mint 48 Chrysler T&C.  Those are the two I have most commonly seen it.  In the last year of Mint car collecting, I have only seen ONE PERFECT Mint car and it was the orange 68/9? Corvette.  All others seem to have some kind of paint imperfection, but nothing that looked like the metal was failing.   I have had some old 1/64 cars (like from 90s or 2000s) cars that were affected as well.   I crumbel them up and save the wheels and any parts that are salvageable.

Here is an Ertl Cobra that is pretty bad . No it was not dropped . I have another like this in kit form in a sealed box and I am afraid to open it . I have a lot of die cast and this is the only one that has this problem .

Wow.  I asssume this only happens to some cars that maybe had a bad batch of metal or bad paint prep.  At least I hope so given the number of 1/18 and 1/24 diecast I have in my collection.

I have only ever had this happens once, it was a white FM '57 Bonneville.

Wow ! I have never seen anything like this before.  I assume this is the metal that is falling apart under the paint?

While I have no diecast collectables,  I do have plenty of Hubley kits. Has this ever been known to happen to Hubley metal?

I have a cheap '63 Vette in metallic red that's exhibiting "rash" under the paint. Only problem I've seen so far (knock wood, or styrene, or potmetal).
