Hi, I want to paint the inside of my fog lights yellow. My plan is to drop them in a bucket of gasoline to soften the adhesive so I can pull the lights apart. Any of you Mudders have a better idea? This is what I am doing...... This was written by Daniel Stern the lighting guru...... If you want selective yellow lights for whatever reason, applying a coating to an optical element is a more permanent, optically cleaner option that eliminates the need to find and get special bulbs. Good results have been obtained by removing the lamps, cleaning the lenses thoroughly and making sure they're warm, then spraying them with several wet-but-not-drippy coats of Dupli-Color Metalcast yellow, a transparent yellow paint product with good adhesion and durability. Let each coat "flash off" (dry most of the way) before applying the next, and use thin coats so you don't get drips and sags in the wet paint. With each successive coat, the yellow tint will grow deeper. Make it about 2 shades deeper than you think looks right, and it'll turn out well in the end. Of course, the coating needs to be permitted to dry and harden completely before you take the fog lamps out on the road, otherwise dust and grit will become embedded in the still-tacky surface. In the case of lamps with removable lenses, by coating the interior surface of the lens obviously answers questions of coating durability against pitting and scratching.
