hp-15C faceplate

[Mark H. Shin]

I have a 10C which had some of the same appearance as your 15C...

The face plate is actually painted on top of the base aluminum.

Therefore, if you carefully mask the display and the logo, you can use a paint thinner/cleaner (I recommend XTREME AK470 Thinner & Cleaner and hobby masking tape available at any hobby shop) with a Q-Tip to remove the entire paint layer, at which point you'll be left with original base aluminum. I would recommend against sanding, as that would negatively affect the original brushed aluminum look!

Which makes it look much better...



Edit: I was planning to airbrush it with new paint (Stainless Steel; also by XTREME), but the look of the original brushed aluminum grew on me and decided to keep as is...
