4 litres will do the outside and engine bay , 6 is best if you want to do the entire interior as well . You probably could do less but I like to have a good paint thickness .

Not that I'm aware of , over here it's illegal to paint 2K outdoors (or out of a filtered paint booth) due to the chemical's involved . Someone else may know more though .

Not bad , don't use there quick drying enamels though as they don't hold their shine as well as acrylics or better enamels , it's good if you keep polishing it though . The quick drying enamel is more of an industrial paint (machinery, tractors etc) , but I've just sprayed the camper van we sold to my sister in law with it , it's a good hard paint with moderate shine , perfect for a campervan but maybe not a mini .

Personally I'd use ppg paints and undercoats for a mini , their paints are good and I know a few professionals that swear by them .

thanks for your info, I see some offer 2k systems that dont contain the nasty stuff & dont need an oven to cure, any info on these for home use?

sounds a lot easier to use lacquer paints, but if a 2k system for home use is available that gives the advantages of hardness, quick drying & good shine i would be interseted

73GT,

Check to see what the NZ authorities allow you to use. I am painting my 65 Deluxe in Acrylic. Would like to use 2-pak but it has a LONG drying time of 12-14 hours at 20 degrees C. Normally 2 pak is baked in an oven for 45 minutes @ 60 degrees C - and I don't have access to a spray booth.
If you can hire a booth or find someone willing to do it for you, I would certainly go the 2 pak route.

Acrylic flashes off in 7 minutes, can be handled and taped in 4 hours and can be polished in 24 hours. Will need extra work to flatten and polish to a good shine. I use a 'Supercryl 111' which is now made by Wattyl (used to be BASF). Haven't tried 'septone' paints but there body filler stuff is great!

My mini will spend its life garaged and out of the sun. Acrylic does breakdown with UV, so consider this if your car will spend alot of time parked on the street. Listen to both sides of the argument as there are valid reasons for and against both types of painting systems.

Here is some shots of my car from last week:

This is 'off the gun' and has not been buffed yet (not that you would buff the boot or interior anyway).

6 litres should do a complete Mini.

There are brands that bring out auto 2 pack that doesn't need a booth. It dries in 2-4 hours and needs to be recoated within 8-12 hours. Anytime after that can destroy the process. There are a couple of problems though, you can't spray any 2 pack paint at home because it is illegal. The drying time is 2-4 hours so there is plenty of time for dust and bugs to land on it.

I done my 2pak at home :? didnt know if it was illegal or not, if your not applying clear coat i dont think dust can stay on it for to long, small dust particles on landed on mine after i sprayed the clear coat, however they can be sanded and buffed out.

With the 6l people are saying that is required, is this just for one coat? Or for a few layers?
Author:  sports850 [ Wed Jul 30, 2008 11:58 am ]
Post subject: 
That's several layers . I can't remember how many "gun's full" it took me per coat but think it would be around a liter per coat for the outside .

I used around 4 ltrs...gave about 3-4 coats on the body and around 2 coats of the inside. I used about the same amount of clear.

The paint suppliers said no problem selling 2K for home use in NZ.
A charcoal repirator will be fine for low usage.
Will 3L be enough to paint the outside only, 2 coats minimum?
Do i need a clear top coat?

look at it this way,delay painting and save up for the extra ltrs you will be kick your own ass when you accidently buff through the layers into primer.
And trust me i wouldn't be painting 2k with just a charcoal mask,it's your lungs,!1yr ago a fella was found dead in has garage spraying 2k as some products use cynide as a catylast to set the paint off.
Im a steam fitter and turner by trade i work for a tourist railway and have just painted a steam loco and that required 38 ltrs of paint and clear,Im just about to paint another :lol: .
I sprayed an xy mocky for a friend and that use's 12ltr of wild violet and clear,it not worth using too little product.
Acrylic is the best way to go for home use,and yes you can getaway with a charcoal canister mask.
if you want a 2k look then there are many clear coats (iso clears) that require a hardner that will give you the same finish,but the clear will alter the colour slightly..
you will only require a clear if the colour is a metalic,which means you will have to spray it with no peal and give at least 3-4 coats of clear light rub with 1200 before the last wet coat.
hope this help's
ps be safe as these are harmful product ,even if it is just one time!
cheers Anthony

While I'm unsure of the legalities of spraying 2K at home, I know Motospray make a iso-free 2K, and an iso-free 2K Clear (which can be used over acrylics). The Iso-free part means is does not contain isocyanate.

Here's some info on the clears:
http://hichem.com.au/hicheminfo/PIDS/Two_pack/Ifc3.pdf

And MSDS info:
http://hichem.com.au/hicheminfo/MSDS/IS ... FINISH.pdf

With all that said, there's not much wrong with acrylic, doesn't last as long and takes a bit more work to get a good shine, but it's safe, easy and a proven way to do it at home.

as far as legalities of spraying in general acrylic/2 pack ect it's classed as "beyond the scope of the hobbiest", here in victoria anyway.....
so spraying at home is a no no! as you can't meet the regulations for epa and residential........

So you'll have to sneak it in or have good neighbours :wink:
