Cellulose or 2 pack?

[skyedriver]

Hi, need to paint my car.
I have used celly on a few cars in the past (1980's & 90's) and always got a reasonable result although not as good a shine as folks seem to get with 2pack.
Now if I go to 2 pack I need to relearn the technique apparently, I don't know the mix ratios, how long it takes to go off, how long I can leave it in the gun and I don't have an airfed mask.
But I want a decent finish.
Do I stick with celly?? I am willing to learn but don't want to cause myself undue agro (and death)

You have no choice than to use a mask with 2 pack.
I'm not sure if you also need an oven to get a proper finish.
Having a car with 2 pack I would not want to have celly again. See if you can find a spray shop willing to have you assist in the job.
Maybe even evening class.

On the Isle of Skye, ....all we have is midges!

Seriously will do it myself but just needed a bit of advice, if it dries in a couple of minutes (same time as celly) I would possibly do it outside. Did a BMW in the 90's outside on a calm day (in the north east of England, granted, and got a good result. Presumably 2 pack in the outside is a lot less dangerous. Alternatively would one of those masks with filters (like a gas mask) be ok, or MUST it be air fed?

2-pack every time

Without an oven you need a "winter activator" and as for the mix you buy a mixing stick that has the ratios on it (paint to this mark, hardener here, thinners here. Couldn't be easier)

You can leave it in the gun between coats, but no longer

Technique is different to celly, put each subsequent coat on thicker, but don't change the mix. Start with a very light coat (so you can still see the primer (this will depend to a certain extent on colour))

Old style cellulose seems hard to come by these days. Modern single pack stuff now polyester based.

Just resprayed most of my Quantum with single pack polyester. It's a mica colour so also needed a single pack clear coat.

It was done outside with a cheap small compressor, and all it needed was a rub down with 1200 wet or dry and a good buff with T-Cut to get a finish that's as good as 2-pack.

Took longer of course, but I think it's still probably the best option for us DIY types with limited means.

2 pack paints will kill you you have to suit up and boot up then get a respirator air supply mask not from the compressor the Isocyanate in the paint will get into your skin if not suited properly weeing blood is not funny I had to stop spraying because of the Isocyanate breath it in with a cheap face mask is asking for problems it will lodge in your airways and games up its not worth it pay the price and get a garage Bodyshop to take on the risk. Some people talk about spraying outside forget it and you can not spray under 70C as Cellouse will go hard and become brittle and crack over time as for 2 pack it needs an oven a proper dedicated place with filters to collect the deadly toxic spray particles body shops have to comply to tough laws because its so dangerous. You have to give 2 pack spraying great respect or it will kill you normally within 15 years of inhaling or getting it into your skin big tip don't touch it .

I suspect the OP may well have made their decision in the intervening sixteen years since this thread was started. Good of you to join up to contribute, though, painting with 2k is not something that should be done without the correct equipment.

Advice still valid - personally I don't use 2-pack unless working in a full extraction/filtered professional spray booth with a full face mask/paper suite etc. Many would say use an air-fed mask too but I find them cumbersome.
