Painting a car

[Zyros]

Hey, ive sanded a few pannels back on my car..
Sanded it all the way back to the original primer, has a few steel patches too unfortunatly.

I wet and dryed it when sanding, and then went over it afterwards with 800grit to smooth it all out.

I bought a whole tin of wax and grease remover, to get all the shit off the car..

(am i doing everything right?)

The car's a trueno, use to be red but the paint job was awfull.
Now, i dont want to pay someone to paint it..
So going to do it myself, so was thinking of a black colour, like matt black cause its easy to do.

I was thinking, seeing as i have all these can's laying around home of Matt black + primer, (Like literally thousands of them), would it be okay to do the car in can's rather than a compressor (as i dont own one)

Would it make much difference really?? If i done it evenly, and its all preped the same.

And would i have to give the matt black some sort of protective coat afterwards?

you can paint a car with spray cans, for sure. if you know how to paint then you can do a pretty decent job of it. often you get munters doing real crap jobs of matt black cos its "phat drift spec yo" but usually this is just because they haven't done any prep work and didn't take their time actually painting it, just wanted to have it ready for friday night or whatever.

so yeah, to conclude, if you prep and take care, then you should be able to get a good job from cans.

do it inside if you can, and in dry weather (not humid or raining), if you do it inside, put a dehumidifier in the garage if you have one and can get away with it.

do you realise how many cans you will go through?
Cans also coat in a very uneven manner, and splatter everywhere.
Stuff in a can also is softer than normal car paint (2-pac is very hard compare to it). If you are experienced with painting then hire a compressor and a gun and paint this way, at the end of the day it will work out cheaper because you will not have to do it second time, and result in a lot less wasted paint, although painting something in matt black will definitely result in a second repaint.

Cans tend to fade with excessive UV too.

[Zyros]

Oh okay,

Well i was either thinking of Satin Black or Matt Black.
Whats your thoughts?

Is there some sort of protective coat i can use?

Yeah, a garage and never let it see light

Hiring a compressor is by far the best bet, its not all that pricey and you'll do a much much better job.

Yeap you can get clearcote, doesnt really stop the UV as such though.

For just about the same price as hiring a compressor, go and buy one, $100. from super cheap. Go to your local paint company, and ask for mistints, i got 4L of 2 pak meatallic black, for my last car for 2 dozen tui. and buy a HVLP (high volume low pressure) spray gun at the same time, i paid $85 for mine. Then you only need thinners, and hardener (if you use 2 pak) and a good filtered mask. At the end of the day if you stuff it up, it makes a good base coat.

you will also need a water trap inline from the compressor or if you use non water based paints it will cause the paint not to stick as good and even bubble it, but if your hire one for spraying im sure it would come with one

yep thats a way better way to do it, cans will look shit in 6 months time and you will want to do it again even if you pay for the paint you can do the whole car for like 3-4 hundred bucks, if you got no experience on a gun then paint some cardbaord with cheep paint first to get the feel of the gun, and way yo go suggest you seal off the metal bits with a primer of some sort then scuff it back upp with your 800 sand paper. if you want specifics then pm me

A little compressor like that would probably do just as bad a job as spray cans

[Akane]

I did my car in a can, it didn't come out half bad.

but cans don't atomise the paint as well as a good compressor. And they're expensive ($40/can).

If you're doing a whole car, it's cheaper to buy a ok compressor then sell it off after you finished it.

[Zyros]

Yeah, im taking my time sanding, i sanded the bonnet and boot right back to original primer!!

But its a waste of time, just going to do it so the gloss is off the original paint.
I primered the bonnet with can's, and concluded.. they're shit!!

It spitted shit out everywhere at random times (Nozzle was a bit $&#$%, so replaced it, and still done the same)

And near the end of the can, it just spat paint blob's everywhere so i have 90% even coat and the 10% is $&#$%..

So going to sand it back lightly, and use a compressor to do the rest of the car!

Might even buy Gloss - Black on trademe, $80.

I disagree, my gun needs 2cfm at 70psi, with a 1.25mm nozzle, to give a 25 micron coat. My supercheap $100 compressor produces 4cfm at up to 105psi. More than enough to do the job. The only way you can produce a shit job, is if you dont know what you are doing.

when spraying with cans (just in general, not nesc a car) it pays to either place them near a heater (not too close) or in a bucket of hot water fora bit before spraying. This helps the atomisation and gives a more even coat.

Ive always used a compressor for all but touchups (now use one for them also) but with cans if you got a good enough coating, then colour sand, cut and buff, as one does with lacquers you would get a good enough finish. But as said, it generally wont last as long.

Prep is 99% of the job. If you dont prep well it makes no figg difference what one uses as it will turn to poo.

imo a small compressor is fine as long as you give it a chance to keep up - spraying a big vehicle the smallest supercheap (or whatever brand - I see them all over the show) one does struggle a little. I have one of them and a much larger compressor also. I usually hook them both up together to ensure I get a good full constant air supply.

Cheap paint, wether from a can or compressor wont last as long as better quality, but higher priced paint.

also as said, if you have never used a gun before get some practice in. Its not hard to stuff upon first attempts.

also buy/hire a filter mask. its bad shit really & I know some pretty young people in the trade who didnt wear them and are a little bung.

[Zyros]

I know how to paint, done a course on spraying car's.
But, the spray can's turn to shit, you dony get a good even flow of air comming out the can at times.

Thanks for the tips guys!

Really the problem with small compressors is that they are direct drive. Once they have been going for 30mins, they get damn toasty and you end up with heaps of water in the tank, in the lines and coming out with your paint.

Hire one of them big belt drive mothers, they dont cost much for a weekend, and buy a $100 gun

I'd run a water trap with every/any compressor. Also a thinner air line as big ones can form condensation also.

But bigger is better in this case yes.

I just painted my engine bay and inside of the bonnet etc ant you can see on yhe bonnet where the compressor has got hot and started to spit water, its a supercheep one it sprays fine but you gotta deal with the water, hire if you want but its only one off so dont mess up the job!
