| 441931 | 2006-03-30 04:33:00 | what does surface rust under the battery on LH inner guard on my car mean? the WOF place said it requires attention SOON and not NOW. So how much do u think it'll cost to fix it and how long would it take? | lance4k (4644) | ||
| 441932 | 2006-03-30 05:06:00 | Rust quite often has an 'iceberg' effect - most is hidden below. I would remove the battery, get a wire brush and start scrubbing. Depending on what you find you may get away with sanding it down and then applying some rust inhibitor (see Repco) then repaint for protection. If you find some rather large holes then a quote from the panelbeater will be in order. No way anyone can even guess how much without seeing the damage. If of course it is near the battery then once the rust problem is fixed then the source of the problem would probably be due to battery acid. Do you have a powder build up on the battery posts, simply washing down with water causes the acid to sit below the battery - therefore the cause of rust. |

| 441936 | 2006-03-30 17:51:00 | Good point, Cicero . . . but they need to neutralize the effects of the battery acid first! After the battery is out, wash down the whole area with a solution of vinegar and water . . . about 50:50 for good results . The acid in the vinegar will help neutralize the battery acid . . . amphoteric ( . wikipedia . org/wiki/Amphoteric" target="_blank">en . wikipedia . org) acid process I think, and then wash the whole area again with a strong alkali soap and water solution . . . use tri-sodium phosphate if you can find it . Then dry it well in the sun and paint it again with a good oil-based paint (if you can find it yet in NZ . . . it is outlawed here in SoCal) . I don't suggest the zinc base paint . There are already too many galvanic reactions going on here . . why add another? Going to assume here that this inner panel top which you are referring is called an inner fender panel, over which the battery holder mounts . I suggest you get to the root of the acid getting onto the panel in the first place . The battery sounds like it is gassing too highly, or leaking . All batteries gas as they charge/discharge and the vents are designed to relieve the pressure that builds up in the battery itself . Over-charging or even overfilling the cells can cause electrolyte to escape from the cells . . . the drip resulting in corrosion where it is not supposed to be . Some (Japanese) vehicles even have a plastic tray under the battery that is supposed to take any leakage to a less damageable area via a drain tube . . . usually under the vehicle and out of sight . You might want to check that out too . |
