A quick bit of advice from the painters out there if you don't mind please.
I've painted a bonnet matt black using rattle cans through the whole process. It was sanded back to bare metal, 1 coat of etch primer, 3 coats of red oxide primer, flatted back using 500 grade, and then 3 coats of matt black.
The finish is nice and level but is obviously a bit rough to the touch. What is recommended to get that nice smooth finish on matt black?
Thanks.

there's nothing you can really do to a matt or satin finish, you're stuck with whatever you get out of the gun - sanding it would leave it looking "sanded", and any kind of rubbing compound would make it shiny.
Matt black will always be a bit rough, perhaps you were looking for more of a satin finish? If so just knock it back with some 500 and go at it with a coat of satin.
Why not just paint it the same as the rest of the car? If you're happy to put several coats of primer and do some flatting back etc it seems a waste to cover it in bodge matt black!

yeah thats what happens with cans ..idealy you want a spray gun ,. cool temps and a slow thinner so it doesnt dry the instant it hits the panel

Plus taking it back to bare metal, matte black is normally porous like primer so you'll have a rusty bonnet soon

Thanks peeps.
I'm basing my question on other cars I've seen. In Runcorn there was a Ford Probe in matt that was smooth (must have looked a kn** running my hand over it) a couple of years back and at Oulton there was a Ford Focus in matt. They were both as matt as mine but as smooth as a modern paint job. Just wanted that kind of texture.
The car is an old Cortina mk4 estate which are pretty low value, so it isn't worth getting it done professionally. I'm just making sure it's solid, rust free, and retro...

I'm edging my bets here as matt black is, well matt!! use grade 600 wet n dry with plenty of soapy water, rub it down plenty, then apply satin black, rub down and apply another coat. Not giving you any guarantees mind, but best o luck

The car is an old Cortina mk4 estate which are pretty low value, so it isn't worth getting it done professionally. I'm just making sure it's solid, rust free, and retro... I wouldn't say they're low value, far from it. If it's a solid colour, go out and find a good paint shop who'll match the colour in celly (a lot of places still do it, regardless of what people think) you'll get a much better finish. 3-4 good coats in celly, then block it/DA it back with wet n dry 1000, 1500 then 2000, mop it up and it will come up lovely. Take the bonnet off when you do it too. You can rattle can it but it's cheaper to borrow a compressor and spraygun or even a HVLP spray station (Earlex) which is very good for chucking celly on. If you're 100% on shat blacking it, wet the floor and do it outside under a gazebo etc.and make sure the primered surface is smooth and clean. That's all you can do really. |

Plus taking it back to bare metal, matte black is normally porous like primer so you'll have a rusty bonnet soon Cheers - hadn't realised that. I normally do all the prep myself then hand over to a bodyshop for the paint side so my knowledge in this area is pretty low. The problem is that a mk4 estate in really good original nick generally only goes for maybe £1 - 2k, so I'd be throwing money away paying good money for a pukka paint job (I have a couple of show cars already). It also has a tired interior and the engine is from a Capri 2.8i that I have in the way - another move away from the originality that gets the good money. I've always fancied doing a bit of a rat look so the matt black appeals this time. I guess the way forward if I stick with this is either a normal solid paint after primer then covered in matt, or to flat the matt and laquer it. I'll have to think about this again..... |

Just rub it down a with wet and dry. Don't worry too much about it being porous I've had lots of matt black machines and they haven't been any worse than any other finish. Sounds like you have done the prep well so all should be ok. ;D

Thanks for the info Chip. As this has been taken to bare metal and none of the primer coats are waterproof I'm not comfortable going forward with a porous top coat too. Maybe you just flatted your normal paint so it remained non-porous?
Someone today mentioned you can get specific matt black lacquer. Never heard of it personally and TBH I've always known lacquer to put a gloss on any colour, but I'll do some research to find out.
Worst case scenario I'm going to flat back, apply a solid paint, then matt black over that. If I'm going through the effort I'm going to make sure the rot doesn't come back.
Cheers peeps.

Oh, and sorry to those I didn't answer about the colour match bit. I don't reckon I can do that as the car is on it's original paint except for a few repair areas over the last 30 years. I really don't think it can be matched, and anything pro done will look far better than the rest.

not tried it myself but you could vinyl wrap the bonnet?
As far as matt paint I've tried a few brands and all were ok. Hammerite satin lasted well but I think their matt is for bbqs. Plastikote do a matt in their 'super' range and their paints last well.
I have heard of matt laquer but not tried it.
