Waxoyl question

[hornmeister2000]

I've got a question about Waxoyl. Basically, I've heard it's a good idea to scrape all the mud off the underside if the car and spray it with waxoyl before the winter. First question is: is this true?

The next question is how to do it. I've asked my garage and he quoted £200+VAT to do it, yet it doesn't appear to be very expensive in Halfrauds so is it a DIY job? My main concern is that it's messy, and what happens if I get it on the wrong bits (brake lines, differential, brakes, etc. Also, what happens if I then need some work doing, either bodywork or mechanical, under the car, and the bits that need doing are all covered in waxoyl? Is there a paint-on version rather than spraying? Anyone got any advice, or should I spend £200 at the garage?

Certainly can't do any harm - it is a DIY job but is soooooo messy! You can just pour it out of the tin and brush it on, but it really is worth injecting the sills etc etc - just thin it down with white spirits and wait for a hot day.

Yes it is a good idea to protect the underside of your car.
You can DIY it and you can paint it on rather than spray it too. (put the can in hot water first to make it eaiser.
Don't worry about getting on brake lines etc.. it just makes them more difficult to remove when they eventually do need replacing. The bit to avoid is the exhaust for obvious fire reasons. Just mask it off with newspaper etc before you do it and it'll be fine. You may well find that there is already a protective finish on the underside of the car which is applied at the factory.. don't remove this unless it is coming off as it is better than the waxol you'll be replacing it with.

It can be a messy job but you are far likely to do a better job than a garage will and it'll cost you a whole lot less. Also you get to see anything that might need doing to the underside before the MOT man gives you a nasty shock.

Waxoyl do a black brush on underseal which has added Waxoyl in it and is sold by Halfords, I've slapped it all over the underside and wheelarches of my Maesty and it's top stuff, certainly no where near as messy as the Waxoyl itself, the original Waxoyl is good but doesn't like gravity too well and can run or drip off on vertical panels. :)

I'd say scrape all the mud off, but small amounts of dirt aren't a problem. Just scrub the underside to get the loose muck off and don't worry.

It's well worth doing for peace of mind and the knowledge that your car won't rust any more underneath, but I would say to check it once a year and 'top up' as required.

Hi Folks,

Three Maestros here. All have waxoyl sprayed inside doors, inside sills, inside boot, bodywork behind front and rear bumpers, inside tailgate. Pretty damn good at preventing rust and slowing it down. Recommmend smothering outside of sills and a thin lip on bottom of doors and wheels arches when the winter and gritters come along. Consequently three maestros with 99% rust free!

Thanks for the advice - do you mean you actually put it on top of the paintwork on the doors? And in the boot? I'm a bit confused about where you actually put it without making a mess or looking messy....

Hornmeister2000,

Yes, literally put a thin strip about 1" along the bottom of doors on the outside. Salt is very corrosive to bare metal, so your bodywork is most vunerable to chips at this point. As the outer sills and bottoms of doors will get salt on then I find it wise to just put a little on while the gritters are out. It does not look very nice, but it it saves your bodywork from rust I can live with that for a while. In reference to the boot. If you lift up the boot carpet you will find several gromits. Lift these out and spray inside these if possible. Also behind carpet where acess to wiring is to the left and right. If at all possible take rear lights off and get plenty in there too.

If you are up for taking the door cards out the inside of the doors at the botoom (Where they all rust) is a prime area for lots of treatment.. Maestro doors tend to rust from inside out.
