i know its bound to have been asked before but i cant find it in the search so.....
my engine bay is covered in a thick yellow coating all around the paintwork/underside of bonnet / hinge/ turrets etc,
i,ve tried using my big diesel pressure washer with degreaser and it wont touch it, even polish / thinners no good. any ideas?? only a paint scraper will fetch it off and i cant do that as its so fiddly and it took me 2 hours to do a 4inch by 2 inch stretch! :cry:

That'll be engine lacquer. Nasty stuff often used by dealers to spruce up an engine bay. Looks great for a while, but after a period of time it goes all yellow and opaque. Its a bitch to get off. Thinners or WD40 with wire wool is what i've always used. Its a slow laborious process...
I'm not aware of anything that will shift it easily without the possibility of damaging the paint beneath.

it only works if it has a brush type end that you can rub in while the steam is coming out

funny this came up, im doing an engine conversion and thought i'd spruce up my bay as well.
basically what i've done is used a tub of white spirit with a cloth, lots of elbow grease and the use of one of them green and yellow sponges your mam uses to do the washing up with.
the yellow stuff came off with a lot of persuasion, and i used a pressure washer to clean off a lot of the grime and muck.mind you my engine is out so i was able to actually jump in the bay, sitting on the subframe and clean thoroughly,it's looking a 100 times better and i cant wait for the engine to go in to see how it all looks.
i'm still not 100 percent pleased with it so a few extra hours tomorrow and a little ring around to see which one of my mates has got a steam washer should have it even better.

has anyone added any laquer as well to bring the shine back up????

ps. mines also alpine white

u can try t cut scratch remover beware this is ultra strong stuff and would take of first layer of laccure.. someone here would confirm this works but apply treatment after use if used.

Tried t cut and farecla they won't even touch it nor thinners only a paint scraper will with hard scraping and that,ll definitely take paint off if I,m not careful. I,ve just had an engine swap so should,ve done it then but wen someone else is swapping it for you in a day you don't really get chance... :eek:

Its actually a protective wax coating applied at the factory.

Some cars are absolutely covered in it and other had it applied sparingly.

Thiners and an abrasive pad will removed it but the paint finish below will go dull. Cutting compound (G3, t-cut etc) will bring it back though.

It's official after 5 hours of scrubbing with an abrasive pad and thinners I,ve given up after just about a turret half done and will just have to live with it under there, until I can afford to pay someone else. It's not like it's just a little bit either the bays caked in it, round the bonnet hinge etc. About a weeks work if you can stick it...... I,ll put pics up tomo..... :-x

Strip the bay other than just the block and head and you will end up with something like this,

And with a bit of hard work you will end up with something like this! :D
