Another modeler brought this to my attention.
I have a few kits Monogram & AMT that have developed Pitting in the Chrome. The Chrome is dissappearing leaving bare spots where you can see the original plastic color. The problem continues and gets worse as time passes. These kits are not more than 5 or 6 years old. Some built some still in the box.
I have some 30+ year old models that have this problem, really bad.
Anyone else have this problem? Know what causes this?

The helmet of my Red baron turned red completely, i could wipe the rest of the chrome of with a cloth!!! I had similar problems with other Monogram kits. Don't know what causes this.  |

back when i live at my parents house all my kits were built in the basement. over a period of time , most of the cars lost the chrome ,or really just dulled up. for me , i think it was the light coating of dust from the basement ,and the dust picking up small oily particles (my father did electronic repairs in the basement) because of that i started buying the old johan showcases to protect my builds and that stopped the problem . i havent seen any chrome loss on any kits i've purchased lately, though

One of the cars that had the chrome problem had been in a case for 3 or 4 months, another has been out of the case for about the same amount of time. Both have had the problem get worse during this time.
A friend had some chrome still on the tree in the box and it started losing the chrome in small spots also.
I wonder how common this problem is and if there is a way to avoid it?

If the chrome is disappearing its always a chemical reaction - like putting it into Castrol or bleach - just lots slower. Chrome is usually very resistant against the oxygen in the air (typical rust/oxydation) - but as soon as its combined with other substances the problems begin. It was in the beginning of modelling a problem to touch the parts and they solved it over many years with some clear paint sealing over the chrome … but this sealing has to be thick enough… Do you have some kind of humidity with a small amount of "bleaching substances" in it ? (For example near the sea you have often a salty atmosphere…) Near a washing machine, near your garage, living in humid surrounding and a factory nearby … Or a shop using chemical substances ? Maybe you´ve heard of most books and papers are going to be destroyed of some acid reaction that eats slowly all paper produced during the last 100 years - means the bleach thats in the paper reacts slowly with the humidity of your breathing, the fingers, air humidity or humidity from drying laundry. Bibliothecs have giant problems with that - in the future there will remain only few written things of the 19th, 20th and probably 21st century …… we will disappear in the future ! Even medival texts and books will survive much longer… Maybe this atmosphere is caused by humidity and the substances within the modelboxes or the literature you have near by ? And then its attacking slowly your kits - especially the ones which have maybe a thinner clear protection. Ask in your pharmacy if they have some simple environmental test that can check the air in you house. Markus |

I have about 400 unbuilt kits in 1:24 and 1:25 scale, lots of big scale also, and I never had that problem... During the years I had the kits stored in a basement ( a little humid down there ), in a garage and even in a garden schack. And as mentioned, I never had that problem???
Must be because of our clean, northern air ;D ;D ;D

I also have a few builds from the 60's that the chrome is beautiful on, both Revell and Monogram.  |

I've never heard of this either ... my Red Baron is from the mid-80s reissue and its still looking pretty good, and several others from around that time look good as well (Pie Wagon is another one). The only chrome that I've seen go bad was the Milk Truck gluebomb I got off eBay ... the rest of the model was pretty dusty, so I just figured it wasn't stored right. The chrome had turned dull and a little milky looking in some areas ... and came off almost entirely on one piece when I went to clean it.
