Got my 2.8 donor with some very cool mods to the engine, suspension and q shift gearbox.
I cleaned and renovated the hood this weekend and the results are superb. It may sound odd but if you want to remove all signs of dirt and mildew then avoid off the shelf stuff and do what I did after following a thread on cardetailing.com
1- Scrub roof with detergent
2- Rinse thoroughly
3- Soak hood in white wine vinegar
4- liberally sprinkle baking soda/ bicarbonate of soda over hood.
5- spray with more vinegar and leave for 4 hours
6- using a soft cloth and a mild bleach/water mix (1-10) wash hood
7- rinse thoroughly (or as I did rinse and go to car wash)
8- Allow to dry and view the amazing results
9- If you want to (I did) wipe in some roof dye with a soft cloth
Sounds crazy and a bit Jamie Oliver but the thing with cleaning mould is that its a living thing and comes back if you just clean it off.
Photo above is pre cleaning and the mildew is visible.
PS. A great mod for the 2.8 is a 325 inlet manifold, it has larger ports and adds significant BHP especially when coupled to a good induction kit like the K&N I fitted this weekend
