So what are you guys using to paint the inside of the box? I've heard potbelly black paint is the bets, but its $26 here for a tin!!!
Whats the cheaper solution?

Depending on what material your box is made of, I usually just use flat black in the front half. Doesnt need to be the most expensive, just a good flat black.
yeah i thought normal flat black on the front would be fine, but i need something for the rear section... My box is made of ply wood, so it tends to bounce the light around the box a bit...
I usually line the inside of the light section with sheet metal flashing. This reflects lost light back, keeps the wood from getting cooked, and it can be bent to cover any parts in the back that need to be shielded from heat.
My house burnt because I put a filament lamp inside a wooden case.
No kidding.
WOW! Thats not good. I have been building them since 04. Never had a problem. Always used sheet metal shielding, never bare wood near the lamp, fans, and did many tests before feeling safe. Always tend the projector when its on.
Any flat/matte paint will do. In my diy I used stick on felt. It doesnt reflect at all. Just do not put it under your light engine and you will be fine.

I am guessing the felt is in the front cool section, I wouldnt want it near the lamp.
I had felt in front and back. My light engine was enclosed in sheet metal though so apart from the actual metal, everything stayed fairly cool. Yah you deff dont want the felt near an open bulb thats for sure. Just use some high temp oven paint. Its dull and can withstand any heat you throw at it.
As you can see in my current LED build I just used flat black spray paint.
