Polish - Metallic paint

[Bushie]

My daughter has an Astra with metallic paint that she want to spend this weekend polishing (we'll see) any recommendations on polish.

Wash it with a heap of kero in the detergent.

A bottle of 3M Finesse, a proper machine buff ( not those cheapass handheld plastic Supercrap ones) and proper foam finger buff pads graded for finishing cut/buff which is usually a fine white foam. DONT USE LAMBSWOOL!!!!
If it's had silicone polish on it before your will need to wipe it down with prepsol first to remove it all.

Make sure you don't do it in the sun and do it while paint is as cool as possible. Masking up is also a good idea.

Once the Finesse has been done, use something like Meguiars Liquid Carnauba Wax on it and buff it off with soft cotton or with a foam polishing pad.
Can be a big job but done properly once, makes it so much easier to keep looking top notch.

Well, IMO i would be more inclined to get a clay bar and clean the paint and then wax it. the old school "cut and polish" might have been fine on cars without a clear coat. Cut and polishing a car with a clear coat does sweat FA and damages the clear layer.

Meguires makes some good gear, but they insist you buy the step by step bottles at like $17 a step. bugger that, just get a claybar kit and some wax.

Finesse is a clearcoat polish, it's used by panelshops after blocking and cutting.
Also used for duco to remove swirl marks from second cut prior to sealing.

Why not use Lambswool polisher LMR?

Why not use Lambswool polisher LMR?

Lambswool is only useable for first hard cut on duco and it will swirl like a bitch. On clearcoat it will tear it apart and breakthru into the basecoat plus leave swirls everywhere. As the wool clogs quite quickly and loads up it has a tendency to leave burn marks on the paint from the buildup of paint and polish.

All your intending to do is remove any rough or lightly oxidized paint so you need to use an ultrafine clearcoat finishing polish (Finesse) and a soft swirlfree pad hence the foam finger. These are a Velcro backed pad and will need a Velcro backing disc but well worth it. They will last you a while also, I've had my current set about 6 years and done probably about 15 jobs with the finish pad the worst for wear as it's done the most work. Have only had to use the cut pad two or three times on really bad paint with another 3M cutting compound.

The D2's getting
The treatment when I get home from holidays as it's never been done apart from original delivery by looking at it.
A mate of mine was in the top 5 spray painters in WA and only worked on custom show and resto work for classics and hotrods. Gave me te rundown when I got my first Harley which was good nic but just badly neglected. Bought it back to a show winner without more than a strip clean and polish. The only polishing gear I've ever bought since from an autoshop since is Meguiars Liquid Carnauba as it's got no silicone.

Thanks, I was watching american hot rod yesterday and they were finishing a freshly painted hotrod body with a lambswool polisher. Is that because they are cutting it back to get the really shiny finish?

Could be or using it without a polish after it's been waxed already but this will still produce minor swirls. Best to do it by hand

Yeah, im not sure what they were using, they were using some sort of polish with it. Dont know what it was though.

Being in the smash repair industry, i have never seen a lambswool buff used. We usually use a foam pad for cutting and polishing, and finish it off with a fingerpad, and we do use Finesse.

At home, just for a polish i just use Auto Gylm, good polish, at a good price.

Also used for duco

You been working on some vintage cars LMR?

You and Brian will have heaps to chat about then ;)


Duco was a trade name assigned to a product line of automotive lacquer developed by the DuPont Company in the 1920s. Under the Duco brand, DuPont introduced the first quick drying multi-color line of lacquers made especially for the automotive industry. It was also used in paintings by American artist Jackson Pollock. It is presently used by Nexa Autocolor — formerly ICI Autocolor and now a division of Pittsburgh-based PPG Industries — as a tradename for automotive enamels in Asia.

Duco is still used as an Australian colloquialism for automotive paint. Also in Romania the term was in use with the same meaning until beginning of 2000.

Can you still buy Duco?

Vintage, no but give me a big shed, suppies, tools and a bed and SWMBO probably wouldn't see me for best part of a year!!

I used to have a show detailing business on the side a good few years ago now. Couldn't do it full time as not really enough business to pay the bills, too much yakka now but it did help pay for a few toys over the time I had it.
With some of the high level cars I worked on there was no way I would ever silicone any of them and considering most of them had paintjobs in the $10-20k range, I dont think it would have gone down too well if I did!!

Dunno about Duco as a brand, was never much of a painter but PPG and Spies Hecker are really the only two brands I would ever use.
"Duco" as per your quote is correct but its mostly referred to when paint is an acrylic lacquer as a solid colour. Enamel paint you really don't buff as it glosses off the gun.
