Video tutorial on how to make a cardboard gasket. The type of cardboard that can only be used for this particular gasket is flat cardboard or paperboard which is typically found on cereal boxes, snack packaging, or what I’m using here is from auto parts packaging In the past I’ve used this technique on throttle bodies, intake manifolds, carburetors, valve covers, etc. This type of gasket cannot be used on high heat applications such between the block and head or on exhaust components.

Video tutorial on how to polish tail lights or parking lights using the wet sanding and polishing method. This will allow for removal of any fading or light scratching. Scratches that are deeper cannot be removal, but will be lightened up in most situations. Normally tail light fading isn’t as severe as headlight fading as it doesn’t deal with road debris flying up or bugs. The length of this procedure will normally last about a year, but that will depend on your vehicle’s usage or climate.

Video tutorial on how to sharpen a drill bit. After usage a drill bit can either dull or chip which does not make it cut as efficiently as it should. A drill bit can be resharpened to make it functional again, there is no need to throw it away. Even broken drill bits can be resharpened. This tutorial applies to a standard style drill bit. Make sure you wear safety glasses when doing this procedure. A drill bit angle gauge can be used, but is not necessary. The more practice you get, the better you will become at sharpening drill bits.
