Old? 2k is an old system. If you're wanting up to date then you'll be needing waterbased

And somewhere to spray it, spraying 2k outside is an enviromental hazard and you can be prosecuted for it. It's hardly the most subtle smell in the world either.

Plus you would also preferably want the place you spray heated to avoid leaving you with a soft paint while driving your car for weeks after (although the ripple effect can be fun).

If you're spraying inside, with a heater then you'll also want some form of extraction. While the effects of 2k are cumulative there's no real reason to try and compound the risk by locking yourself in a box with it.

5L of 2k plus thinner and hardener will cost you at least 4 times that of 1k, before any extra ancilleries. That also assumes you have a hvlp kit or compressor and gun.

2k is no longer (in the UK) supposed to be sold for automotive painting purposes.

There's extensive proof that 1k systems last for at least 5 years without difficulty on a daily drive. Many people don't even own a car that long.

If you are unpractised in spraying, there's a good chance you're unpractised in sanding too. Aside from the fact that the thicker the paint the slower it dries, if you start hamfistedly sanding back any paint you'll end up with no paint and have to start again.
In the case of 2k this usually means the whole panel as blending is hard and definitely not a beginners job.

1k systems don't 'need' a clear coat. That wasn't the question or reasoning for the OP's question.
Nice as your marginally incomprehensible post was, it's not really relevent in any way.

Steering back on topic though...
Spoke to a nice lass from Dulux today, she told me that none of their clear systems are really designed for use with the exterior paints.
They offer a yacht varnish, high gloss finish and works with their high gloss so should be fine with rusto also.
She did say though that there's a chance of clouding of the finish (happens with clear coats sometimes) and it won't offer improved durability over the weathershield product which is good for 8-10years as an exterior covering.

It's also completely compatible with the trade high gloss, so I might get a pot myself and see how they compare.

[new_zealand _minis]

yes i know waterbased is the way forward but wont come in everywhere for few years

all depends on what 1k system you are talking about not needing clear

all the benifit of 2 pac is that you can trust it dries all the way through . not needing to leave it weeks to dry all the way through like 1k

i know you are ment to spray 2 pac in a stable enviroment . but there is no reason why you cant spray in you drive way . no heat needed

have all body shops in the uk gone to watherbased . is that why you cant buy 2pac ?

[Skortchio]

You can definitely paint 2k on a driveway but you'll risk getting fined if anyone reports it plus 2k takes a long time to dry unaided, depending on how thick you coat of course.

As far as I understand, 2k has been phased out of automotive spraying now with celly soon to follow. The auto shops are the first to be hit, if you want to buy 2k yourself you have to agree (sometimes sign) to say you understand the health risks and aren't going to use it for auto spraying.

enamel, celly and solvent don't need clear coats unless pearl / metallic. Having the clear coat can be handy to mask small imperfections from driving but it adds to the hassle when repairing them too.

the weathershield product which is good for 8-10years as an exterior covering.

just a thought...how many houses move at 60 mph??!! say if the paint chips is there going to be any problems with lifting?
just thinkin out loud!!

[Skortchio]

That's currently the unknown factor. Conversely, how many Minis are battered by Uk weather everyday? Once cured, I'd imagine (and hoping ) the paint is well adhered to the layer below. I've not had any lifting problems while wet sanding it so far with a days drying time between so it seems pretty safe. Time will however tell.

Rusto has been tested pretty thoroughly, a google of roller painting car will give you 100's of links for that.
The Dulux thing came, initially from a coach painter who reccommended it for use on long boats and barges as well as carriages. River boats take an absolute pounding so can only summise it's up to the job.

If it's not, it only cost me £50 all in so not a major catastrophe

[midridge2]

There is alot of miss information in this thread.
In England celly has not been used in bodyshops for years, 2k was used in bodyshops and new cars for many years after celly as it was "better" than celly but waterbased then took over about 10 years ago.
any one can still buy 2k or celly with no fuss but some 2k colours are not easy to get as the mixing tints are running out.

2k dries due to a chemical reaction so does not takes weeks etc to dry. it does not need heat to dry.2k
(1k systems don't 'need' a clear coat. That wasn't the question or reasoning for the OP's question.) not correct, if its a base coat it will need clear coat.

[Skortchio]

A couple of places I enquired at had a clause you had to tick to state you wouldn't be using 2k products for automotive use and that you understood the health risks.

I did point out that pearl or metallic base coats would need a clear coat top if painted in celly, where as gloss colours don't. :)

[Bungle]

you say you don't need much to spray 2 pack and it's easy but

i have rollered my camper on my front lawn, there is almost no smell and the only mess is a few drips onto the grass

where as spraying

the neighbour is going to complain about the smell, the noise of the compressor and the fact that their front garden is now blue

to me spraying doesn't work

Back in 09 I sprayed the 25 in silver rustoleum over the top of the flatted down roller job I did a few years previously. I then sprayed a yatch varnish over the top and then polished. It wasn't a show winning paint finish, but it was more than good enough.
The problems all started though in the spring of 2010 after it had spent the winter out in the snow were some of the flat areas and roof stated to go funny. What appeared to happen was the clear was cracking and crasing taking some of the siver with it.
It got so bad that I ended up sanding it back down last year and dusting over with hammerite spray cans.

[Minidarren83]

Well it looks like I've got my answer if I roller paint it there pretty much isn't a clear that can go over it I might just have to bite the bullet and make my garage a spray booth. Skotchio where in Essex are you I might have to pop over when your done and see the Finnish you get my car is going to be white so will be very forgiving lol

I'm in Basildon, fella. Only round the corner

Going to pop to the Dulux centre tomorrow and quiz them some more about the increased durability of the weathershielf line, maybe give that a go for the last few coats.

[danie garry]

just as an experiment you could get some 1k lacquer, mix it into the dulux and brush away! see what happens(on a test panel of course!!)
