No you can't do it in that order.You can put cellulose found in aerosol cans on top of 2K paint without any problems,but put 2k on tp of of cellulose and it'll react like a biatch.You can put a barrier coat on to seperate the two,but all things considered it's be easier to use all cellulose or all 2K for primer and topcoats.

Chris.

P.S. I hope you're not spraying 2K at home as it can be a killer if not used correctly?

2k aint a base coat is it?

i would not use 2k unless you are in a proper enviroment.

2k can kill. (no joke)

i have used it and will be using it.

2k clear over 1k base.

Two pack paint still has to be thinned but needs an activator mixed with it before it'll go hard,kinda like runny coloured Araldite.Cellulose which also has to be thinned is air drying (it's solvent evaporates) but doesn't need the activator or catalyst to start the proccess.

1K I've always understood to be the same as cellulose as it just means 1 pack,2K means 2 pack as it needs the activator which 1K doesn't.

yea im aware of the dangers of 2pk paints, iv done abit of research about it already,im just thinking about getting into it, as my passenger wing and rear bumper could do with being done, and with the money i would spend on getting them done at a body shop i could easily buy the guns and a cheap commpressor etc etc and it would be fun at the same time and i could also use them in the future :)

so which paint would be better for diy, or which has the best finish? im guessing 2pk is harder wearing ? as it requires hardener.

Cellulose if you don't want to end up in a wooden box pushing up the daisies[+o(].2K is more difficult for the amateur to get a decent finish and is harder so more difficult to polish,if done right cellulose is easier for the DIYer to get a good gun finish as this is.......

If you don't get it right it's softer so easier to flat and polish.

The reason 2K is so dangerous is because it's got isocyanates in the hardener,which for any given quantity is 400 times more toxic than cellulose[:O].

nice job there, looks smoooth!, thanks for the advice, i will be staying away from 2pk if thats the case, no point in risking it when i could use cellulose. did you use a plastic primer on that? or just normal cellulose primer?

You can use any other type of paint (in theory) on top of 2K because once it's hardened it becomes inert and no further chemical reactions can take place (again in theory).Cellulose or any other air drying paint is always active and can be "re-activated" by adding more of it's solvent (thinners) which is why you can't put other types of paint on top of it.

To be 100% safe if you don't know just don't mix paint types in one place and you won't have any problems.

Thank you,there's plenty more to come this year and I had such a stupid idea today that it's so secret I made myself forget what it is until it's time to do it[:cool:][:DD].
