A question for v12 guys

  • I'm trying to clean up under the bonnet & I've recently noticed some pictures of nicely detailed engines, my question,


    what is the best product to make the black plastic come back to life?


    as mine is a bit grey looking:hmmmm:

    Those who risk nothing,achieve nothing,become nothing.

  • Meguiar's Tire wall shine (purple gel) works very well, and is what I and many I know use.

    If I misspelled a word it's because I'm Norwegian, so bear with me.

  • Hi Steve, I use an aerospace protectant which is pretty much what detailers use over here (despite it being a US product).


    The aim of the game is to keep the plastic black with a satin sheen... Using stuff like tyre gels and oil based products is dirt/dust etc will love to attach itself to the sticky residue created by the product...thats not what we really want...


    I order my stuff by phone but will try to find a weblink straight to it. :)

  • I use Meguiar's Hyper Dressing on plastic parts under the hood. Hyper Dressing is water based and hence isn't a dust magnet like most silicon or oil based products. The product can be diluted with water to change the finish:


    • High gloss 1:1
    • Medium gloss 2:1
    • Satin finish 3:1
    • Natural finish 4:1


    I use Hyper Dressing in a 4:1 diluted solution because I really don't like glossy or wet look engine parts. I'm very happy with the results, but I'm quite sure there are many other similar products - probably a lot cheaper than Meguiar's. The reason I use Meguiar's is because a friend used it so I knew the results were good and I didn't want to waste time experimenting with other products :mrgreen:.

  • Although I have much bigger fish to fry at the moment, I have a question about engine bay detailing :harhar:


    Does anyone know how to get the horrid yellowy crud off the engine and engine bay paint? I think it was some kind of protective coating but it looks vile.


    Also, I have a pentosin leak below the reservoir and there's a lot of dirty oil around that area, how can I best clean it off? I have a pressure washer, but I'm worried I'll force water into electrical things and the car will never run again. Any ideas?

  • soda blasting is the way most have been done but co2 blasting is the latest method. no debris to clean up except the crud of cause.
    looks like Steve 840 will have to change his sig.

  • I have comprehensively blasted my engine bay with no ill effects what so ever. Use some Gunk or similar and if you can take her for a good run to dry things out a bit....
    I always use a can of WD40 on the whole engine bay as some detergents react with all the alloy parts in there...


    As for the Cosmoline issue, if you can remove the part use some Nitromors. I used it on my intake manifolds and dizzy covers as well as the plastic parts... A good blast with lots of water afterwards though.....


    Hope this helps

  • re engine block and bay detailing its quite straight forwards... but takes time... i have to spend time covering floors over with sheeting etc to collect everything that drops through!


    Normally i first run an engine until warm (loosens oils and grime slightly) then cover over all exposed wiring / ECUs etc with a tough plastic wrap which doesnt tear unlike foils...then i use meguiars All purpose cleaner or a citrus mix diluted to about half with water, spritz the entire engine and bay - if its really bad then i work half at a time. Leave the solution for 5-10 mins and aggrevate with a soft brush the really heavily soiled areas. Then with a pressure washer set to around half pressure, give it a good blast off... passing an area 2-3 times. Then i go round with white cloths and dry it all off and inspect to see if areas need more attention.


    After i like to seal any paint with acrylic sealant and dress any plastics and rubber as the degreasers remove any protection originally on the surfaces.


    Now-a-days i use a steam cleaner...it takes less time but forking out for a decent SC isnt worth it unless your doing it fairly regularly.


    Hope this helps some peops!
