    Default Spray Coating Removal?

    On my newly aquired 348 there appears to be like a silicone spray on coating over huge chunks of the engine, particularily the plastic parts.
    An engine dressing "gone bad" ? Like there is grit and grime embedded in it...
    Anyway, it looks unsightly (a polite version of my real opinion)

    On non textured surfaces, I can "piggle" it with my finger nail, (photo below is 5mins work)

    But on textured surfaces, that wont work. And hence makes it look unloved.

    The "conventional" degreasers wont touch it. Any chemical suggestions, please? I dont want to call in an airstrike and damage the stuff underneath with something too "good", but I do want to shift it (though preferbly insitu)

    Matt,

    I'm afraid it looks like a lot of patience will be required. One of the pro-detailers may be able to help.

    I'd maybe try softening it with a steamer before attacking it..........M

    I wonder if someone has been trying to make their engine shiny with something like WD40 and its fried on????

    I would be tempted to try various solvents such as meths or white spirit to see if anything affects it then away you go :-)

    I agree, it does look like its been an attempt to make shiny thats baked on, I know its >5yrs old because its not the former keeper's handywork.
    The good news is it can be defeated (slightly) with Nail Varnish remover. (stolen from eldest daughter)
    The bad news is , only very very slowly.
    The worse news is, on further inspection, its everywhere...

    So.. I do need something a bit more "industrial" and am probably going to have to take bits off to go at them.

    Default engine coating

    Hi Matt

    It looks like clear lacquer to me. Back in the day when I was working for BMW it was one of the things we used to apply to make the engine bay look good as new.

    Its looks good for a while very glossy and wet look but when it gets old this happens. Your only option is to try and strip it off but you may end up rubbing it back and simply re painting it. This will be fine on the black metal parts but harder to do on the plastics.
    You may have to smooth down the plastic bits and then re-spray with more clear lacquer you can get it from Halfords or other car places it's high temp stuff.

    Hope this helps

    This is only an idea but could the components be taken off and sandblasted/bead blasted? I know you can strip various surfaces with different media and different pressures. You will probably have to replace much of the rubber components.

    You can buy small component bead blaster booths and nut shell media for soft blasting.

    Get one off ebay and then sell it again when you have finished.

    Have to make sure no media reached the engine!

    Oh dear, I hope it doesn't come to that.

    I think I'll try as irarref suggested, a range of solvents, and also see if I can find what that clear laquer is that justinjgy mentioned - so that I may better know my enemy.
    But with a BH Weekend incoming, I want to tie down a couple of projects (and hence get "stuff" ordered) - so might park "engine" whilst I try solvents and move to something simple like the electrics.

    Thanks for the ideas so far, chaps.

    This is the type of product I was thinking of.

    Try a Tar and glue remover that might break it down.

    Good luck over the weekend Im working on a F430 with a long list of things to clean too.

    Thanks.
    Spookily I emailed Hycote today to ask, if it was there stuff, what would they recommend to remove it.
    They suggested Xylene, Paint Thinners or Acetone. Going to try thinners on the grounds that I can get it in town.
    So my weekend plan is - wet = engine. Dry = electrics (garage is only wide enough for 1 door open, but plenty tall enough for engine bay open.)

    Oh, and I need to finish putting a wired data point in the garage, don't really need it, but I cant get on my high horse with Nosevi until I do.
    Good luck with your list too, and thanks.
