Undersealing

[Frikkin Evil]

I'm planning to treat and protect the underside of the car. The car is an import, and as far as I am aware, has never been sealed. It's always looked clean underneath, but now there's a little surface rust I want to get it sorted before it resembles the Titanic.

What is the best method in this instance? I presume I am best to remove and neutralise the existing rust and then coat over with something like waxoyl?

What products/tools etc. are best suited to the task?

Cheerz.

wire brush it off and take it to formula 1 tyres and exhausts... £30 and hey presto.. made a cracking job of mine.

just like silverspeed said wire brush of all the lite rust and waxoyl the lot, i do my car every summer put it up on axel stands take off all the wheels arch liners and clean and reseal. i found not to use the pressure tin, the sprayer gets blocked as the waxoyl cools and things tend to get very messy and it makes thins *BLEEP*ty when you need to remove them(ive learnt from experiance) what i do now is put a concrete slab or a few bricks in the oven heat them for half an hour ,then if you have an old metal baking tray that the mrs doesn't mind you using!! put the bricks underneath the baking tray to keep the waxoyl nice and runny, oh yeh warm the oil up as well
this will keep the oil workable for about 2 or so hours possilbly longer on a sunny day plenty of time to do all of the underside of the car.
to apply the oil i use small foam rollers from a cheap shop and a radiator brush to get underneath pipes and petrol tank, i also do all the suspension joints nuts and bolts and the brake hubs as well its amazing how much difference it makes when you come to take something of 2-3 years later and theres no corrosion to foil your plans, hope this makes sense started this last night while drunk and now finishing of hungover

Thanks mate, it's appreciated. I've read a few waxoyl horror stories on the net.

What about using an inhibitor before waxoyling?

[cunning stunt]

the waxoyl has a rust inhibitor in it, ive been doing mine now for 4 years once a year and the car is just as good as it was when it came into the contrty

Any advantage to using clear waxoyl?

I think the psychologial aspect of covering everything in black so you can't see the rust might be best for me!

[cunning stunt]

to be honest have only ever used the clear, this stuff can get pretty messy in clear would hate to be able to see where i spill it as well!

Various sections of mine getting some serious rust treatment - cup-brush'd off, etching sealing primer, black paint, stone-chip prevention and this year will be waxoyling. If you've no rust currently, I'd just jump straight to the waxoyl and get it done ASAP before you end up with a job like this!

I've yet to do a proper survey of the 'dark side of the Four', but I did notice some rust when it was up on the ramps recently.

I shall get the wire brush out and we shall see how bad things are.
