Primer on existing paint??

[WALM]

So etch primer on bare steel and ally, that i understand, but what can you use to prime existing paintwork?

thank you.

Primer?

 

[WALM]

ok but...

Zinc, red oxide, acrylic, epoxy, polyethylene, urethane??

(please bare in mind i am very much an amateur)

Giz a clue, what are you going to be using, celly, 1k, 2k, synth etc? But basically 2k primer can go under any of them, otherwise generally use the same type of primer as the topcoat e.g. synth primer under synth enamel etc etc.
(Just on the offchance, check the 2k sticky, if you're not sure of the H&S implications of it).

You don't necessarily need a primer on old paint.

yeah checked all h&s on the 2k it will be a 2k base and clear (i think), got me air fed suit and ventilation on the way anyway!

it is so confusing! so far i think i need:

etch primer
high build white
shimrin kandy base
kandy top
then a clear with flakes

and a load of hardeners, catalysts and reducers to go with it!

(i basically want a very high gloss metallic finish with lots of depth and good color and flakes to add a slightly custom effect)


if anyone can make sense of how to use those paints i would be grateful
i did phone them and got a general idea but after reading through i'm lost again.

i know im making a good case for myself to stay clear of such expensive and dangerous/hard to use paints, but i'm very keen to learn as i will be spraying regularly in future.

well you are going in the deep end.
i dont think you'll be able to do it,as a novice.

Hi WALM,

Have you done any paintwork before?? If not, I would be inclined to go for a more run of the mill paint job to get used to it first, alas when learning there is always a good chance you'll waste a lot of money, and feel very despondent.

 

[WALM]

I have done several jobs using cellulose paint yes, and a many using aerosol cans and fine grit paper! but i would consider myself a complete beginner really.

i dont think you'll be able to do it,as a novice.

I think that may have been the wrong thing to say!! lol. (got to prove myself now!)

jokes aside, can anyone recommend a way of achieving a quality finish, with a good color, high gloss and slightly metallic?? without going as expensive and complicated as above.

it is to be applied to ally, steel and existing paint.

i have a nice big compressor, all the air and oil filtration in place, a kestrel A7006GSS gravity gun with a 1.6 nozzle, and a budget of about £150 for paint.

 

[jaykay]

you can buy metal flake loose.(ebay)you mix with lacquer.apply a few coat till you get the desired amount.then you build lacquer with out flake to bury it.
but be warned it can take a lot of lacquer to do the job.
£150 is not going to get what you want.

 

[WALM]

ok thanks and the color and primer?

my budget can stretch but i need to be able to change color and achieve the same finish with each one.

i.e. bulk buy the primers and lacquer, but only buy small amounts of different colors.

what kind of cost would i be looking at?

i mean would something like rustoleum combicolor finished with lacquer and flakes work?

i guess the obvious answer is trial and error.

 

[jaykay]

yep

You obviously like a challenge !!!
To be honest you might want to rethink what you have in mind, I use & sell flake and its not really for the novice painter.

You need to get another budget i'm afraid, Candy & Flake is not a cheap paintjob.
To give you an idea of cost i painted my car and the paint & primer came to £900 and thats at trade prices !!!

Not trying to put you off but trying to be realistic.

ok thanks that gives me a good idea, im spraying items smaller than a car, a few aircraft wheels, some wings, seats and other bits and bobs, not all at once but it will become a regular basis.

still not totally put off the expensive paint, i can see it being an issue due to the risk of it going wrong as an expensive mistake, but as far as reading data sheets and following instructions goes, i can do that!

just to add i'm not trying to put down pro sprayers as i know for sure there is immense skill involved, i just gotta start somewhere, and it is more than likely to go catastrophically wrong the first few times!
