Will never polish by hand again (1 Viewer)

[Antony bleasdale]

Treat myself to a dual action polisher and with maguirs oxidation remover, Polish and carnauba wax she looks amazing. Never got anywhere near this finish before?

 

[CazPaul]

Nice one, which model/type of polisher did you go for

 

[Antony bleasdale]

Just a cheep one off eBay. Katsu

The paint finish on a Motorhome is not that thick Maguirs oxidation remover appears to remove some of the paint. Be Ok on gelcoat as its reasonably thick by comparison to MH side walls.,

 

[Antony bleasdale]

It was the gelcoat finish I was struggling with, all good now. Just used polish on the sides which is a different construction

It is pretty normal to clean grp boat hulls (top sides, not below the waterline) with oxalic acid before polishing. That doesn’t take any of the gel coat off. I might try it on my Hymer front as just polishing seems not enough to give a deep finish.
Anyone done this to their van?

I clean the outside of my Motorhome twice a year.

Could I ask why it seems so important to do it on a more regularly ?

?

I have not actually used it on my hull, but I have watched most of my mates at the club use it on older hulls. Yes, toxic stuff, I think its a diluted solution, but will check and advise. I have used oxalic acid crystals on my deck though, where anchor chain and similar rust stains the gel coat. Sprinkle some on, agitate with water and brush to get the marks off - it does - then rinse off with a couple of buckets of sea water. Spotless.
Incidentally, I, and my mates, hand or machine polish depending preference or speed. Most of us with a product called McQuires (I might have mis-spelled that). It does the job very well. Though our chandlery might be an influencing factor in the brand usage!

Meguiars I think you mean, a lot of motorhomers use it too.

Me too. I foam wash before each trip. That's it.

When I had a boat I used a machine simply because 20 metres of GRP was daunting, however with our MHs I prefer doing it by hand so I get close and personal to all the surfaces, it is amazing what you will see. For example I picked up very early the tiniest of pin heads of osmosis on the front GRP cap of the Flair which led to the van going back to the factory for a complete repaint.
Still have the 2 polishers. Thing to be aware of for newbie users on GRP, high speed and too much pressure can lead very quickly to burn marks as the gel overheats, also gel is very thin, not as thin as paint of course however edges could already have been attacked at the factory by enthusiastic finishers and you are at risk of polishing down to the mat. I can point you to examples on my Morelo so take care.

Be very careful which polish you use, use a low cut polish only. Like this Polish

Hi Michael

You would/should need wet and dry to get that far through a gelcoat, sounds like their laminators need a kick up the jacksy.

Maybe Martin, but on one sharp acute edge in the black gel I can see its thin. Admittedly only about 15mm long but I think they have had trouble with the black gel on the new Palace Liner.
Unfortunately not sure how it can be invisibly reinstated.

And also loads of the very best healthy foods that are wonderful for you, greens, nuts, miso, tahini etc

With great difficulty would be the answer but I am surprised that there is a problem on sharp outside edges as these are of course inside corners during the moulding process so more prone to thick than thin.
