Product Suggestion

I thought today was a good day, but then I started removing vinyl from 10 signs I'm making, and EVERY.SINGLE.ONE.BLED!!!  What I thought was good wood for my signs (whiteboard) turned into a major fail.  Today I feel defeated!!!  My plea to Rust-Oleum ~ can you make gel pens or touch-up pens in a medium tip that matches your spray paints (specifically in Blossom White and Canyon Black - my MOST used colors), but all other colors would be fine too.  I can't throw this wood away because I invested a healthy about of $$$ into it, and I will make it work come h*ll or high water ~ I'm stubborn that way!

P.S.  My next board will be Baltic Birch ~ fingers crossed no bleeding!
