Hi. Just went to Halfords today for some supplies. Bought some Autoglym High Gloss finish which I put on after the SRP. Car looks great. I also bought some Autoglym Engine and Machine cleaner. I've never cleaned an engine bay before but I want to see how clean I can get my Alfa. The videos make it look straightforward but I'm a bit concerned about spraying water into my engine bay. Has anyone got any tips or warnings before I take the plunge next weekend?
