Piston Slap: The Sentra's Salt Assault
TTAC commentator greaseyknight writes:
I have a question that I would like to throw at you and the Best and Brightest. Time is of the essence! In about a month I will be moving from the PNW to Wisconsin. My car is a rust free ’92 Nissan Sentra, and I would like to keep it that way during my stay in that state, which is be at least a couple years.
I really have no idea what precautions I should take being from the PNW, where under car rust is a totally foreign concept. I have heard of various under body treatments like Fluid Film and others, but what should I use? I really enjoy the piston slap articles, keep up the good work!
First, let’s be clear on one thing: rustproofing is pointless for folks who keep their car for 10-ish years. Second, the B13 Sentra is a sweet little machine, totally worth keeping around for the rest of your life. For special cases like you, consider a rust proofing, undercoating spray from a shop that does such things.
If done correctly (i.e. not blocking up drain holes in the body) these sprays are a great idea for an older car with cherry metal. They probably will not save every nut and bolt from the Rust Devil, but major components will be far better off. Let’s say that you move to Wisconsin for more than two years: don’t worry, if all else fails you can replace any bolt-on component using the magic power of the Internets and loyal followers of the Sentra (and its Mexican twin, Señor Tsuru) while the spray-on undercoating protects the rest.
Other things I recommend?
- Mud Flaps installed using the factory holes in the wheel arches…if possible, as that makes future removal far cleaner. If not, drill the holes and PAINT the exposed metal before installing. The Mad Tite stance and golden wheels below are optional, naturally.
Off to you, Best and Brightest.

- TMA1 How much did exchange rates affect this decision? The Renegade is imported from Italy. I'm wondering if that's what caused the price to reach within a few hundred of the much bigger Compass. Kind of a no-brainer to pick the larger, more modern vehicle.
- CEastwood Everytime I see one of these I think there's a dummie who could have bought a real car , but has to say look at me driving this cool thing I can't drive in the rain like an actual motorcycle that I should have bought in the first place ! It's not Batman I see driving these - it's middle age Fatman .
- SilverCoupe I should be the potential audience for this (current A5 owner, considering an S5 in the future), but I can't say it excites me. I have never liked the vertical bars in the grilles of sporting Mercedes models, for one thing. The interior doesn't speak to me either.I would be more likely to consider a BMW 4 Series, though not the current version with the double Edsel grille. Still, I suppose it would be worth a look when the time comes to replace my current vehicle.
- Verbal Can we expect this model to help M-B improve on finishing 29th out of 30 brands in CR's recent reliability survey?
- Lou_BC I kept wanted to say "Book 'Em Danno" while looking at the photos of the Mercury but this car predate Hawaii Five - O by 3 years.
