Well I have always been scared to wash a engine of a vehicle with large amounts of water, due to possible damage. This weekend I attended a detailing seminar thrown by the Pros of Detail King. They took the worry out of engine detailing and made these 2 engines look great it was amazing. 1. Make sure there is soapy water on the fenders of the car. 2. Put zip lock bag around alternator/fuse box 3. Spray the whole engine bay with wd40 all over the spark plug wires especially. 4. Put your favortie degreaser all over engine. 5. Spray down whole engine after product has set and stand back to a nice bright engine. 6. Done spray down underneath hood if it has the cloth material mat or it will fall down. 7. Rinse fender down Heavily. 8. Dress engine. The two engines turned out to be amazing. The one product they used for the engine I really liked it alot. this 15 minute job can bring in a good amount of cash for that short time. Start doing engines.
