Zamac Rot

One of my favorite BMW civilian cars.

Back in August of 2020 I posted an article about zamac rot. In a nutshell, what happens is that the model’s metal body starts to bubble underneath the paint. That occurs when the zamac alloy contains impurities, mainly lead, that react with the other metals. That reaction produces an intercrystalline corrosion process, with corrosion bubbles appearing inside the metal. Ambient temperature and humidity play a roll in the process, speeding up or delaying the reaction. The problem is that if the zamac alloy is contaminated with lead, the process will eventually occur, sooner or later.

When I got it out of the cabinet, to my dismay, there it was: zamac rot.

Usually, you don’t see zamac rot with higher end brands, yet some manufactures are notorious for this. Franklin Mint is perhaps the most famous. And until now, I never heard of this happening to Kyosho. However, as you can see from the photos, my beloved M3 GTR has fallen victim to the problem 😭. I took it out of the cabinet a few days ago for a shoot of another model and there it was, zamac rot. So, what am I going to do about it? Nothing. There’s nothing to be done, the process will get worse and the model eventually may crumble to pieces 💀.

Sometimes the process stops there, but I’ve seen models actually fall apart with time.

The only solution would be to replace it. However, a proper silver M3 GTR is really hard to come by. Minichamps offers the model in a few colors, and they’re very easy to find. Nonetheless, since BMW produced the real car only in silver, Minichamps’ models are all wrong. So unless I find a new Kyosho in good condition (very rare), or some other brand issues the car in 1:43, I can’t replace it.

Boogers 😖.

Books – Racing In The Dark

“RACING IN THE DARK: When The Bentley Boys Conquered Le Mans” – Peter Grimsdale

I have a confession to make. Until very recently, in my eyes Bentley was just a “cheaper Rolls Royce”. Yeah, they had a lot of victories at Le Mans and won again in 2003, nonetheless for the last 50 or 60 years it was just a luxury brand. Very good cars, no doubt, yet only a luxury brand. However, that view changed a lot after I read Peter Grimsdale’s book. With a fluid and enticing writing, Grimsdale showed me the story of W. O. Bentley, and his saga to make a great car. And he did – with blood, sweat and tears he made what was at the time, probably THE best sports car in the market.

Unfortunately though, financial strife ended his dream, to the point where the once great Bentley Motors became a cheaper Rolls Royce 😣. I truly loved the book – honestly, without a doubt the best car book I read in the last couple of years. A hardback with not too many photos (unfortunately), it is easily available at Amazon. Despite the title, I would say this book would be for all motorsports enthusiasts.
