 Celly!!

 

It's a simple equation really, if you have the facilities (including an air fed mask) then use 2k, but if not then use celly.

2K is nasty stuff. Not worth the risk if you don't have the equipment. But the down side to cellulose now is the cost of the paint in the first place. Might be worth costing up the options. If you prep it yourself & have a shop just do the 2K paint? 2K does give a very good finish very quickly. Cellulose takes some work to look good.

Id go for 2k personally, a really good quality filter mask, cover all suit, gloves and wrap around goggles will do the job as your only painting one mini, if you were doing it day in day out then air fed mask is a must

For an official point of view:

Nitro-cellulose paint

This is the most common "classic" or older car finish. It's ease of use and relatively hardwearing characteristics made it popular with manufacturers and repairers alike. Although toxic, it can be applied with basic breathing apparatus and with relatively cheap spraying equipment. Essentially it is a system which is not designed to produce a final finish "out of the spray gun". Rather, once applied, it needs to be polished by varying degrees to achieve a high gloss shine. Unlike more modern paint systems, it can be applied by brush, although the best effect is achieved by spraying. This paint type dries through a process of evaporation.

Two-pack or Isocyanate paint

This paint system was first used extensively during the 1970's and 1980's. The paint is extremely toxic. Isocyanate is a respiratory sensitiser so inhalation can affect breathing, with potentially fatal results. For this reason, this particular system is not normally suitable for application by DIY enthusiasts, as it requires special breathing equipment. Drying is assisted by the use of a hardener (the second part of the two pack system), although evaporation takes place also, preferably in a heated spray booth or oven. This paint type is very hardwearing and produces a finish straight from the spray gun, so cutting application times.

Water based paint

This system is the most common type in use by manufacturers and repairers today. The colour coat is water based but still needs to be protected by a two-pack type clear or lacquer coating. Being water based it is more environmentally friendly. Because of the mixture of paint types, repair is difficult for the DIY painter.

Before undertaking repairs yourself it is advisable to seek professional advice from a qualified vehicle painter or paint shop supplier.

May also be worth considering rustoleum, I've not done it myself but after seeing some of the results on youtube and cars on here...

It looks like an interesting alternative.

[Daz1968]

Have you considered the 2k non iso paint, think the hardener basically turns 2k paint into 1k acrylic. I have used it with 2k primer with results better than cellulose high build. I have some clear to try it with but not got round to it yet.
You could even use water based and top with a 1k acrylic clear.

Another way of looking at it is: are you giving your neighbours masks as well?

I know 2 pack gives a superior finish, but is it worth it?

Daz is that the 2K with the valspar unibinder ? veering towards celly from a safety perspective, not just mine, but other neighbours ( and the dog )

[Daz1968]

Yes the valspar product, it works ok in primer but doesn't harden like true 2k covers well but best sanded wet as it clogs the paper I would say it's better than cellulose though, think it's what most places provide in aerosols now. I am going to try some in direct gloss 2k when I get chance, it's just thick so paint needs over thinning to spray I added about 30% 2k thinner, it flashed off quick though

[sam7]

2k is the only way to go for a durable lasting finish!!!!

 

but is all dependable on how much experience you have with it. a lot of people are completly petrified of using it on here but if u r carefull and take proper precautions u can do it safely in ur garage at home,

good filter mask £20-30

tyvek sprayers suit £5

[midridge2]

cost of funeral for not using a air fed mask=£3,000

[sam7]

bit drastic!!! unless ur extremely stupid with it.

 

but ill give a good example of what it can do, a friend of mine is a sprayer aswell, he didnt like using masks because they were uncomfortable and would use a poxy dust mask instead. he smokes and drinks alot aswell, but he was respraying a car and started feeling very ill. ended up in hospital for about 2 weeks. think it was due to smoking/drinking and spraying, not spraying individually.but still made him very ill. still alive luckily and is still spraying., and still with out a mask. but a good example of what it can do

IF ABUSED AND WITHOUT A MASK!!!!!!!!

 

but i think this arguement has been gone over and over and over.

 

so ur choice mate!!! if u have sprayed a bit before u no ur self if ur going ahead with 2k. 

celly isnt a choice in my mind, but thats just me.

i use the stuff everyday and havnt had a problem with it.

Please stop giving potentially hazardous advice to other users. What you do to your own health is your own business, but don't tell others to not worry about techniques that are clearly hazardous. Fact is that professional spray shops use specially sealed and evacuated rooms for spraying for a reason. Just because something doesn't kill you on the spot doesn't mean it does not have a negative impact on your health. Even just a regular spray can can have serious ill effects in a closed space.

[tiger99]

Yes, well said, a filter mask DOES NOT give any protection against isocyanates in 2 pack, and I am sick of people saying that it will. People will die if they follow advice like that.
