orbital buffers!

Evening all..

just a quick one, I've been neglecting the car recently with work and using the works car for trips away, so she's in need of some love.

I want to start buffing the car to rectify swirls and some bizarre minute rippling in the paint's surface, and don't want to spend £200 on a Meguiars buffer for the few times I'll be able to use it!

Is there an affordable one on the market that won't truly mess up the finish I could go for?

Cheers!

Re: orbital buffers!

Despite having an orbital buffer that cost in the region of £150 for all the gear I always use my rotary polisher which cost about £30. I tend to use soft pads which makes it pretty safe.

The rippling you mention, if that's orange peel then you really need to use rubbing compound / wet and dry to flat the area, I wouldn't waste your time with an orbital buffer. Be careful if you're going to attempt to fix it.

Re: orbital buffers!

Hi Martijn,

I hope you are well.

If you looking to remove swirls then you could go with a Porter Cable (PC) which you might pick up cheaper than the Megs G220, although once you have bought pads and polishes it will be a good £180+.

Some Rotary polishers work out a lot less but be very careful as if you have never used one before you could easily cause big problems to your GTVs paintwork. Although some rotary polishers appear very cheap you have to make sure that they have a decent RPM range, as you need to be able to work the polishes at a reasonably low speed to refine the finish after you have carried out defect removal.

As Mr_Caine said, I think this is the orange peel effect that you are talking about. I would strongly advise against trying to rectify this yourself if you have never wet sanded and machine polished as you could very easily end up with some knackered paintwork. Even as a pro it is not always possible to remove the orange peel effect as so much depends on paint depth, condition, type and also whether the orange peel is infact in the clear coat or colour.

If you remind me where you are then I can let you know of someone who could correct the paint for you. I'm not saying that you need a detailer every time but I think on this occassion it would probably be a good idea.

If you do fancy doing it yourself then I suggest getting a few scrap panels and refining your technique first as you can then leave all your bad attempts on some scrappy panel rather than a stunning GTV!

Cheers,

Roy

I've had one of the 2 handed & 1 handed smaller jobbies. Pretty good really but not as good as getting a pro (like Roy) in

Re: orbital buffers!

The G220 is about £140 for the base unit, but when I bought mine I went for the advanced kit from Meguiars G220 Dual Action Polishing Machine - Meguiars Car Care and Detailing Products

Came with loads of pads, masking tape e.t.c...all stuff you would need.

I see it as an investment, as I can use it on all my cars and the results are fantastic (I use with a combination of Meguiars/ClearKote products).

Amazing at removing swirl marks from paint

Re: orbital buffers!

I have a Porter Cable too and agree completely with TSE....

...though I just noticed he is a pro!

cheers, roy, sensible advice as ever! I'm no expert, but my panels have all gone a bit "crinkly".. never looked like that before!

It was resprayed about 8 - 9 months ago..

might have a word with the bodyshop and see what they say, any grounds for getting them to rectify it?

Re: orbital buffers!

Can you get some photos up of the "crinkly" panels? - very interested to see.

I too have a Porter Cable 7424 RO. All up including transformer, pads and (menzerna) polishes was about AU$600. I was of the same mind as you however - couldn't justify the cost for the single session of removing the swirls in the paint. The thing is though, regardless of how carefully you wash your car, in any real context it's pretty much inevitable that some paint swirling will return (especially given the softness of AR paint). I give my car a full going over annually, but have also used it multiple times for RIDS that seem to appear from time to time. So worth the cost IMO.

Re: orbital buffers!

Sounds like the paint has reacted with whatever was on there before.

Re: orbital buffers!

Hi Martijn,

Yep would be good to see photos of the panels, as this sounds a bit extreme for just orange peel.

Re: orbital buffers!

here are the photos, bear in mind this is really fine, took the photos on super macro with the lens practically touching the paint!

The first two are different shots of the same panel, and the third gives a more "normal" view of the same bit.

Re: orbital buffers!

The effect in the second picture is known as 'fanning'. It's a pattern caused by the incorrect air pressure from the spray gun. Looks as though theres overspray aswell.

Third picture looks okay.

the car was resprayed 8 months ago, and i've got to be honest, this is only now really becoming noticeable- would you say it's worth going back the the bodyshop?

Re: orbital buffers!

You can try but I doubt they'll accept the car back after eight months.

Can you take picture 2 again from directly above instead of an angle and in good light, I just want to see if that is overspray.

Re: orbital buffers!

Since someone mentioned cheap polishers i thought i would link this in Car Buffer Polisher Polishing Sander w/3 Sponge Pad Kit on eBay, also Cleaning, Waxing Valeting, Car Care, Car Accessories, Cars, Parts Vehicles (end time 09-Jun-08 12:37:00 BST) its probably not that great but it does have variable speed as TSE mentioned
