Was just curious as to how I would go about doing this I've already sanded and polished the side covers but am not sure how to do the top part of the engine due to the edges and vents. Any ideas
I used a wire cup brush on an angle grinder to get all the crap and paint/lacquer off my engines and a small wire brush and abrasive papers etc. Be carefull as you go, wear gloves and eye protection as the wire bristles fly off like little darts. You can get rotary wire brush's for your drill etc too but its slower.
I use Glass Beads in my sand blaster. There is also crushed walnut shell for sand blasters. These smaller and softer media do not harm the metal. silica and aluminum oxide and ferrous oxide media will bore right through the aluminum. Also stay away from crushed glass too.
Glass Beads are round and will bounce off any hard surface.
