We have a pit at work & i'm been thinking more about the idea of having a crack at waxoyling the underside of my car. For the price of a tin, you can't knock it.
Chatting to the chap who runs the garage, they also have the kit to spray on the stuff, rather than brush it on, which makes things even easier.
As well as this, they have a very powerful jetwash.
Looking on youtube & reading some guides i found, i found you've to clean the underside of the car 1st before waxoyl application (such as spray/wash & also wire brushing rust off)
So my question is this:
1. What should i really be avoiding spray/washing under the car? If anything. I suppose common sense would don't send blasts of water from direct under the engine. Anywhere else?
2. Anything i should NOT apply waxoyl to? I've read the exhaust as that will stink & peel with the heat. But what else shouldn't be getting applied?
Anyone else here had a bash? Reckon it's worthwhile?
