do you have a pic of your engine now as it sits? because depending on what you like or what you want your engine to look like will kinda help with some ideas. ive seen white cars that have the cover painted gloss white with red and black letters ive seen blue and red flames and ives seen some pretty ugly covers lol you can either make your bay look better or make it worse depending on how and what you do... the outcome all comes down to the prep work if you spend hours sanding smoothing and just fine detailing it will come out great. also if you get your cover painted by a shop or where you can get a high gloss clear over what ever colors you do it will also make it last longer and look that much better
