Brera 2.4 jdtm

Meguirís Ultimate Compund

Next time I have some spare time I want to tackle my black Brera’s bodywork issues. Mainly surface scratches and swirl marks which are doing my head in, and I will probably be doing the entire car by hand as machine polishers scare me!

Had a quick look and it seems this Meguirs stuff might be the one I’m looking for and was wondering if anyone has used it and how were the results, or do you recommend a better product suited for the black paint the Brera’s came with?

I've used it but never found it that good to be honest. If you want to remove the swirls you might struggle by hand. I used to favour AG SRP to fill swirls but on the black cars Poorboys black hole is excellent with AG EGP over the top. They also do a swirl remover but I've yet to try it.

I am not a fan of it either as a one-step correction on black paint. It is fine on cars that are more forgiving of minor marring. I'm afraid that, for decent results, the truth is you need to take more time and more steps with black finishes.

The really simple answer is that, whatever product you use, you won't get that far doing it by hand. And, even if you can, it will take forever. If you have black paint, as I do on my Spider, you'll be spending a lot of your life removing marring of one sort or another because it is so damn visible! I would strongly suggest you invest in a DA machine.

But first, there's a difference between compound (which is abrasive and which polishes the surface) and things like Black Hole (which are fillers that mask flaws but which are not abrasive). Black Hole does not correct swirls but masks them. None the worse for that but not a permanent fix.

There is nothing to fear from DA polishers provided that you are sensible. I'd agree that the old machine mops with sheepskin pads can be lethal in the hands of an amateur but a DA polisher does not stick in one place and it takes determination to get one to burn through paint in normal use. There are plenty of YouTube videos around on technique; this chap can be a bit long-winded but he knows his stuff and you won't go wrong following his advice - https://www.youtube.com/playlist?lis...A_rJTf2-fD7UPH.

I use a DA polisher and Koch Chemie stuff. KC provides an index showing the level of abrasiveness and degree of polish on its products - all explained here: Productsystem | Koch-Chemie. There is a range of compounds and polishes of varying strengths and it is best to start off gently, say with the anti-hologram compound or something like Rosa, which are barely abrasive. If that is not removing the marring, move up to one of the lighter compounds and only move to heavy stuff if that doesn't shift.

Every time you use one of these abrasives, you are removing a small amount of clear coat so it is always best to start off with as un-abrasive a formulation as you can get away with.

IIRC Slim's Detailing sells a DA machine with a Koch Chemie starter kit so you don't bankrupt yourself buying preparations you don't need. in2detailing does a similar kit for less than £150.

Other brands that I like include the Detailing Kingdom - https://www.in2detailing.co.uk/manuf...iling-kingdom/ -which is very workable and leaves a lovely shine. Less abrasive is the Glare range - https://www.glare.com - (which has some of the properties of a glaze), which I believe is suitable for cars with little clear coat left as it is much less abrasive than traditional compounds.

BTW, before doing anything to your paint, you should decontaminate it, not only by washing it but also removing embedded contaminants, ideally with a clay bar and specialist iron and tar chemical removers and then ensuring its absolute cleanliness by applying panel wipe just before putting pad to paint.

I'm sorry it's not easier but this is one of the reasons why so many people shy away from black paint on cars.

Thanks for that, some good info there.

I might just get a professional to take it on if it doesn’t cost too much. If I were to go down the diy route with machine polishing I would need to buy a spare door or something in my colour to practice on first!

Sure.

Depending on how long you wish to keep the Brera and how bad the paint is, getting a pro to do it might be sensible. But I'd warn you that doing the job properly would probably cost twice or thrice as much as that DA kit and a scrappy door. However, if it were done once and then immediately sealed with a ceramic or similar coating you'd get at least two or three years of relatively pain-free wash maintenance and some resistance to swirling. Something like Kamikaze Enrei -

OTH, you can use the DA on other and subsequent cars and periodically to apply wax finishes to them once polished...

personally i think if you're not experienced get a pro to do it, it might cost you a bit but it is possible to make a complete mess if you don't know what you're doing. not only can you make the scratches worse if you use too much compound but you can polish through on the panel edges. A d.a. is ok for finishing with something like 3M anti-hologram polish with dark blue top but if your paint is scratched you need to start with something courser and a proper mop. A good detailer is your best bet
