Hi Kev
I'm no language student but I remember the instructions
First of all wash the caravan to remove dirt, grit, grease and oily residue etc and dry the surface using a chamois leather and squeegee.
Polish with Stage 2 which is very mildly abrasive to remove stubborn marks, use a slightly dampened lint free cloth to apply the polish and when it dries white, buff it off using a good microfibre dry cloth.
Apply the wax in manageable squares, give the bottle a good shake and use a dry cloth for the wax. On the caravan I use the windows to mark the position and the decal which is half way up the side of the caravan so that I can divide the surface into rectangles because it can be difficult to see where you've got to.
Wax one rectangle at a time, it will dull the paintwork and then buff that rectangle to a good shine with a clean dry microfibre buffing cloth before moving on to the next section then do the front and rear panels.
Try to choose a mild dry day, not too cold so that the wax will buff up better.
The wax shine should last about 3 months, no need to polish next time just wash down and re-wax.
If you are feeling particularly energetic you could apply 2 coats of wax, buff the first coat, re-wax and re-buff and the wax will give a good shine which will protect the polished surface beneath.
The idea is to gradually build up a good coat of wax so the use of polish is not necessary, just wash down regularly and wax every three months or whenever the mood takes you.
