Can other drivers download or re-use my paints on the Trading Paints website?

The paints shown in your My Paints section are private to you unless you choose to submit them to the Showroom. Paints submitted to the Showroom are made available to other Trading Paints users for viewing or assigning to race on their accounts without modification.

The only time paints in My Paints will appear to other users is when you race in iRacing.
