Mod Podge is an alternative to Mister Super Clear, It is a water-based product, meaning you can easily clean it off while wet if it gets on something. While it isn't toxic like MSC, it still has it's downsides. (this covers the downsides well!) You can also use Mod Podge to give finished customs a certain finish as Mod Podge comes in many different finishes.

Good for customization because..

 * Can act both like a glue and a sealer.
