Really don't know what to suggest about the trifire being a funny git but I just seen on another mod how to remove the paint from corsair ram, I thought it was anodised but looks like they are painted.
Remove the red bits at the top, paint stripper applied with paint brush, wire brush to help get it off, paint wise I would do an ultra light coat of primer like 1 quick pass & do a light but thorough coat of colour of choice or leave bare metal, avoid metallic paint as it needs a coat of clear laquer.
It's what I would do personally if I had that ram & wanted a different colour.
