Detailing engine bay - ideas or recommendations?
« on: 27 March 2020, 08:45 AM »
With the engine out of the car it's the perfect time to clean up the engine bay.  As usial, I'm struggling with how far to take it.  Someone more committed and rigorous than myself would certainly strip everything out and respray it all.  Unfortunately I won't be doing that, just too long and tedious.  Anyway, it's a driver, not a show car, and most of it is pretty good.  It's been pretty well degreased and pressure washed.   I've got a real steam cleaner to help finish the job and properly matched 2k paint for touch ups.  I don't mind removing simple stuff like washer pumps to get into nooks and crannies. 
Question (and I know this sounds insane):  has anybody every brushed 2k paint instead of spraying?  It might be more convenient for some touch ups. 

Thoughts, ideas and suggestions welcome!  Thanks,
-Dave

On the right hand side you can remove the battery tray, overflow tank,  headlight washer hoses if you have them, and the major electrical wires. . If you then unclamp the hydro lines you can joggle them around and wrap in tin foil. You may be able to unbolt the front hydro valve to get the lines further out. Detach cruise control. That will allow you to get a vast large area.

The left side remove ignition box, starter resistors, coil and bracket,and many wires can be removed and pushed out of the way.

wrap anything left in tinfoil and spray away.

I used Simple Green and parts cleaner brush to remove all the oily stuff.

If you're referring to actual 2 Komponent single stage paint, then yes it can be applied with a foam brush.  Though, if you're using a metallic single stage the metal flake will end up being uneven in application.  If you're using a base coat/clear coat paint then I can't comment.  I avoid base coat/clear coat like the plague.  So I never work with it.

It is exactly as you describe:  2 component, single stage.  I'll play around with it.  I do have a very small spray gun. 

We're being whipsawed between spring and winter.  Had a few good car days but then it snowed 5" last night.  Needs to be consistently warmer to get to this stuff and it's making me nuts.  Thanks for the comments gents.  I would never have thought of aluminum foil to mask stuff.  Great idea.

I have tried brush painting single stage 2k and the results are terrible with heavy brush marks, runs, bubbles.  And when brushed, colour coverage is poor.

If you are wanting a quick solution with control, use an air brush.

As said it is not a problem to remove or mask what you can't. If you have the engine out it would be an ideal opportunity that I am sure would be regretted later. If you haven't got the necessary spray equipment get a colour match spray can theirs not much to do and it would look great.

Last night I gave it all another look.  True enough, with engine out there's ample opportunity to mask tubing, move wiring out of the way,  etc.  I'll pick up an air brush and have at it.  Thanks for the encouragement.  Too often I'm tempted by the easy way out.  Cheers,

If the engine bay is not too dirty, you can do rinseless wash although you will need lots of MF towels.
