Opened one of my Cobra cabinets and noticed this bad cracking on this die cast. It is an Ertl brand. All others are fin but this one has split very badly. I have another in kit form and that body is fine. Anyone else see this on one of their die cast ? Any idea what happened here ? Seems kind of weird to me. I have some much older in the same cabinet and they are fine. ???????

A few years back there was a thread here about this- somebody had one of the 1:18 Hot Wheels diecasts (IIRC) which was literally falling apart. I can't seem to find that thread now...

Weird. I wonder what is causing this. Seems funny. I have a few hundred die casts and this seems to be the only one with this problem. Maybe I better check my others more closely. I have a bunch still in the original box in cabinets in the garage that I did not look at. Not that there is anything I can do about it now. Could it just be the paint ?

Ray if there not in heat and temp changes then it could be on the manufacturer. sometimes even older cars paint will crack if your temp is warm/hot then cold....

Probably made from a bad batch of Zamak.  It'll corrode and eventually cause the paint to flake off.

Yep, diecast degeneration. Most common causes are humidity, and severe temp changes (causing humidity), oh yeah, and humidity. If you don't have central A/C, it works to run a de-humidifier. Some folks may dis-agree with me, but this is what I've found with my own experiences.

It's just weird that out of the hundreds of cars I have this is the only one. I have another exactly like this one that is fine.

I had an ERTL 1:18 scale Chevrolet Cameo Pick up that literally fell apart. Firts the doors just came of, the the paint started to follow from the truck, and in a couple of weeks the body was loosing pieces.

I have some diecasts, and the only ones that have no bubbles on the paint ar a '67 Fairlane by GMP, a '68 Mustang by Auto Art a '71 Lada by IST, and a '58 Edsel Bermuda by Dambury Mint. All others have at least some tiny bubbles on the paint.

 

My advice to you is to put your love on the plastic models. Another point in favor of them is the fact that you built them and not some diecast company.

If it's only happening to one or two out of a large collection it's a bad batch of metal. In the model train hobby a few years ago whoever was supplying the metal to the train manufacture  provided some tainted material. On a set of passenger cars one set of wheels would crumble and break while the other set was fine on the same car! Traced back to a bad batch of metal......manufacture had to replace them all.  Nothing you can do now....

Yeah, Ray, I'm no metalurgist, but that looks like disintigrating metal to me. If it's the ONLY one you got, I guess you should be thankful, cause even though I've never seen it on a DIE CAST MODEL, I have seen it happen to pot metal. I'd say you got a model cast from a bad patch of pot metal. I DON'T think theres much you can do with it. Be glad ya got TWO! Good move!

It is bad diecast.  I have had way too much experience with it.  Moisture or temperature has nothing to do with the cause, although it may change the time it takes.  There are certain diecast that this is a common on. The Ertl 69 Camaro cars are about the worst, some the entire runs fell apart. It starts out with what looks like uneven patches of diecast under the paint and kind of hard to see. Some will develop small blisters and some will just start cracking.

 

At one time I had a list that was put together by a group of us and there were a few hundred different 1/18 models on it. 

 

The only thing you can do is use parts off of them to modify the ones that didn't fall apart.  

 

I should add that paint rash is another serious issue but that is just the paint and can be buffed out if not too bad. 

 

Very Sad!

In your case, most likely a bad batch. I had it happen to a 1:18 '60 Ford.......that thing looked like a warped promo! I still say that humidity does play a role, but perhaps Tom is right, it may facilitate it's outbreak.

The paint on the roof of my black 1/18 '60 Starliner is cracked and flaking off, but the rest of the car is mint, and the roof is plastic, try to figure that one out. Makes me mad, because the black version with dog dish hub caps was a hobby store exclusive and is kinda rare. At least I can repaint the roof...  but I probably wont.

I stashed some of the Ertl 69 Camaros away in the original master carton when they came in new direct from Ertl. I had three each of the white with orange stripes and three of the orange with white stripes. The were up on the top shelf of our climate controlled stock room four about four years. I opened them and all the white one were cracked up in pieces and the orange ones were perfect. This has happened on numerous cars of mine where I packed them away when new and certain ones are now junk and other in the carton are fine.

 

Most times it's not the entire car.  Some may be the doors and hood while others in the same run could be the body bad and the hood and doors are fine.  

 

Here is a bad hood on a perfect car. You can see the rough finish and blisters. I broke this one with my thumb.

It's a bad batch of diecast. I have a Franklin Mint 60 Rolls Royce that broke in many pieces just sitting on the shelf. Also a Kyosho Audi wagon that broke in half when somebody tried to open a doorand then the door fell off. The Rolls is a total loss and the Audi is glued with a do not touch sign on it. .

 if you contact the company most likely they will make good on the items. forget about danbury and Franklin mints i don't think you will have much luck there.
