MOT

[Russell Wheeler]

Another pass this year. Again another advisory for rust. I rubbed down and hammerited both subframes the other year, but the advisory is for general underbody corrosion. Anyone used lanoguard - my regime of hammerite and wayoil doens't seem to be working (or it's just the car getting older). On top it looks perfect, not a spot of rust.

Would help if you have any pics of the corrosion.

For what it's worth, last year I washed the underside and then gave everything a spray of Dynax UB. I also cleaned out the wheel wells and sprayed them with Dynax S50. The Dynax stuff comes in a can with a long wand attachment with a 360 degree spray head, so it's easy to stick into any cavities and spray. Two coats of each are good.

Once that was dry, for good measure I gave everything a spray of ACF 50. The Dynax should be good for 2 or 3 years, probably more in the wheel wells, so I just respray the underside with ACF 50 annually, as that part only takes about 20 minutes, as you can get under an RX without having to lift it. I also periodically give the underside a rinse with a lawn sprinkler in winter to wash off any road salt.

Points to note. Cover the brakes with a plastic bag before spraying, and put a plastic sheet or cardboard under the car, as the drips (particularly from the ACF 50) will make a mess, and leave for a day or two to dry.

I do all this late Sept/early Oct, as it's just after my annual service and MOT, and ahead of winter without it being too cold to be messsing about.

Yes, pics. Would be helpful for others.

I do...

I like it very much and apply it myself. ( Using ramps ).

When it warms up I will go underneath and have a look.
