So many confuse polishes with waxes or sealants. They do entirely different jobs so below I will try to explain.
Polishes
A polish is designed to cut. By doing so it improves and refines the finish.
Most of you will be familiar with sandpaper ? A polish is a fluid containing particles so like a sandpaper but in a fluid form. Like sandpaper we can get different grades of polish. So the polish we use should have the cut required to give us what we are looking for it to do.
IE if we are polishing out deep scratches a low cut polish will do it but it will take so much longer. We would not choose a sandpaper with little bite to smooth rough timber ?
So care over what you use must be taken or you can remove to much material. Or you could be working hard with little results.
There are two basic types of polish.
The usual are the ones that stay in grade .. This means the size of the grit in the polish stays the same no matter how long or hard you use it. IE you choose a medium cut it stays a medium cut throughout the polishing process .
The their are are the AOIs. These are polishes that as used the cutting grits break down as you polish. IE you start with a medium cut but as you polish the grits break down in size therefore giving a lesser amount of cut.
I prefer the predictability of a polish that stays in grade. With that the level of cut doesn't change so keeps it simple.
Polishes have and leave NO protection to the surface.
Waxes and Sealants.
Both are designed with one job only in mind. That is to add shine and protect the surface.
Which you use makes no difference it's a personal choose. But they are to protect only.
Waxes or sealants have NO cutting ability whatsoever.
There are on motor homes many types of surface.
For GRP or the usual painted areas on them we need just normal automotive car polish. There are many products marketed as specialist kit but trust me these are just re branded re packaged products .
So for GRP , Paint, Headlights and tail lights we need simple automotive polish Not re branded expensive same as but much more expensive.
Glass is a separate entity.
For glass we use Cerium Oxide . This is a powder which we mix with water to give a smooth paste. With CO we can remove both light and deep scratches from glass to restore it to an optical clarity. Even deep scratches inflicted by diamond rings can be removed. It's quite an easy product to use and the results are amazing.
Composite panels on MHs are a grey area for me as I haven't yet had any experience. I will update as this is gained in time.
