Undercarriage Detailing
Well now that I got most of the bugs worked out of my 29 Phaeton I turned to degreasing the undercarriage. For the most part it cleaned up well but I found areas that had oil and grease that had eaten through the paint. So should I just sand and hit it with Rustoleum or would you recommend something different.
Thanks Ron |

Re: Undercarriage Detailing
That paint deterioration is a real pity on an otherwise very nicely detailed underside of your Model A Ford. |

Re: Undercarriage Detailing
It's only paint......I would be concerned if everything was rusty and rotted out. I could take things apart and use my spray gun but my car is a nice driver and not a show car. How would you go about fixing this?

Re: Undercarriage Detailing
I would just sand the lumpy spots smooth, looking for cracks or holes, and if none are found, hit it with black enamel aerosol. I use Plasticote gloss black enamel aerosols. On the muffler I sand lightly, hit with phosphoric rust converter, wipe off with a wet rag when reacted, and then spray with black Plasticote BBQ paint.
I do this on a hoist every few months using a piece of hand held cardboard to stop overspray. I just want the underside to look clean and neat, but not to pass a inspection, since we drive a lot on gravel roads so there are always chipped areas needing touching up. Using a spray gun involves too much work, specially cleaning it afterwards. The aerosol is the work of minutes literally. I always finish by spraying inverted into a waste bin to clear paint from the nozzle so it is ready for action next time. SAJ in NZ |

Re: Undercarriage Detailing
You may want to look into what the cause is of some of your issues, if you haven't already, before you repaint. Looks to me like your carb may have been dripping gas on your wishbone. Do you have engine pans? Just a thought.

*Medium meaning more than a thin spotting, apply enough to get a visible gloss and some minute degree of film flow (the surface can self level), but stopping well short of so much paint you develop sags and runs. This is way easier said than done, especially on vertical surfaces. Practice on some vertical surface scrap if you aren't confident. Review good spray technique if you think you need it. The $3 spray can trigger handles work great, keep paint off your fingers and give better control. Control of the spray pattern and film thickness is key. For a really good job, let the paint harden for 30 days and then wet sand with 800, then 1000, and on up to 1500 or 2,000, then compound to a flawless finish and get the edges well blended. Oh, wait, we aren't obsessing. |

Re: Undercarriage Detailing
My car is a driver also. For under the car I prep like others have suggested and apply Rustoleum Painter's Touch Semi-Gloss with a 4" foam mini-roller. And a brush in hard to get to places.
Not as smooth as spray but less masking involved and all I am trying to do is prevent rust and look decent. Not too many people see the bottom of my car... unless I run them over!!

Re: Undercarriage Detailing
A few more thoughts:
Use bright lights, they show flaws. In tough to reach areas, and areas the spray can't reach like the top of the wishbone, consider brushing the paint. Yup, more steps and more paint cost. Realize that if you get up close and it looks ok from 18 inches, it's going to look fabulous from 10 feet. Who's going to get within 18 inches of your wishbone? Control dust and clean the floor before spraying. If you're going to paint the entire wishbone, then no blending, mask all the edges and go. |

Undercoating cracks over time and allows in water. The end result is major rust. Much worse than what you would have had by leaving the car alone and doing nothing. Ron |

Re: Undercarriage Detailing
It's not your normal under coating, it's oil base creeping oil, check their site
