Save your dried out paint. 

Thanks for the tip. This stuff might pay for itself. Here's something I discovered: Tamiya airbrush cleaner can replenish dried up Testors Metalizer, just like the no longer available Thinner for Metalizer. So glad I kept my dried up bottles of Metalizer.

Fed Guy, something going on YT won't let me reply directly. But here's one place you can get it. www.usagundamstore.com/products/mr-replenishing-agent-for-mr-color

Great tip! Money saver too. Who knew paint was sooo interesting and detailed.

Thanks Terry, good to know that it works well with other brands too.
