Nice! thanks for the link, i'm thining about doing my tank too

 

schooter, is there a reason your afraid of a real spray gun that sprays real paint that isn't that expensive ?

 

Why would you color-sand it after you've applied the clear-coat?

 

+1 & scratches mellon.

 

I painted my gas tank, side covers, and fairing today. For just about everything, minus the gun, was about $80. And that is a lot of extra paint and materials. You could probably do a whole bike for less than 40-50.

 

Depends on what "color sanding " means to you. To me, color sanding is always done to the clear coat. See this article in Hot Rod Mag

Once I apply the paint (base coat) I'll lay down 2-3 coats of clear. Once that is dry enough I block sand it smooth (color sand) then lay down the final coat or two of clear. Then sand again once it is dry and buff. The only difference between the sandings on the clear coat is the grit of paper. On the first clear coat sanding I ussually only use the 800 grit to give the final clear coat something to 'bite' into. For the final color sanding I usually go... 800 or 1000, 1200 or 1500, 2000, buff.

 

Thats always been the proper way I have read. I havent tried it yet, but I will more than likely be doing it today.

 

With the modern 2 pack paints you don't need to sand, they drive cars straight out the booth & never touch them for 20 years.

 

....and you're saying that a human can duplicate the motion of a computer based robotic system exactly and without deviation time after time??? Plus the cars are also put thru a curing oven (if memory serves correct)...go to the custom paint forum (http://www.custompaintforum.com/forum/forum.php) and ask any one of the professionals there how they do it....

 

The guy that painted my bike is well the shit at painting. His bike is goin on 10 years and looks like new mine is 6 years and is great since I don't take any care of it (don't tell him that), Paint done by someone who is good and cares is far better than anything a robot can do yes they do the same thing over and over again but they don't have eyes to see the beauty of a freaking awesome paint job....... Factory paint is meant to be fast and cheap not really good. You can not beat a good paint guy who cares especially if he rides a 650 maxim.....................................................

 

You have to work at getting a Magnificent Paint Job.

The Rods with killer finishes you look at and see yourself reflected in the shine; took more than a robot blowing-on a single stage paint.

Primer went-on twice and got wet sanded.
Color went on a few times and got wet sanded.
Clear went on over the wet sanded color and brings-back the luster.
More clear.
Buff the clear with Diamond Coat.
Polish Buff the finish with a foam pad and finish polish.
Then, they go over the whole job by hand.

 

Ive read that a lot of people do 3-4 coats clear coat - wet sand - 3 or 4 more coats, followed by the whole wet sand-polishing procedure.

 

it does take a bit longer to do spray bomb here is a pic of a bike i did 2 years ago still looks great and it was from cheap walmart spray

 

Unless you paint all the time and have perfected you'r skills,
a color sand (cut and buff) after clear is the way to go.

It will change a mderately inferior job to a nice factory finish,
when using shop quality equipment.

The thing to remember when useing a rattle can is the final "wet"
coat. It takes time and practice to shoot a good wet without a run
and have it mirror back at you.

 

I'm not talking about new cars, I'm saying the repair / respray shops shoot on the clear & don't do another thing & the finish is stunning, but like all things there are levels of perfection, if you have a mirror finish from the gun, why touch it?

 

Because its the difference between a cheap looking paint job to a dynamo paint job.

Humans might be able to duplicate the motions, but the robotics are much more sophisticated and do more than just paint. The amount of paint used by robotics is fairly thin compared to what most humans do.

If you were to spend all the time of doing everything for a good quality paint job, why wouldnt you go through the final step? Even pros cant get it perfect every time. You can bet every show car or bike you see has been wetsanded and buffed like crazy.

 

I'll give you that, but keep in mind what type of paint they are shooting in that situation. If you are matching an existing stock paint they are usually an enamel 1-step paint.
I would be very surprised if you could show me a quality painter who doesn't color sand at some point when using a basecoat/clearcoat paint process. You can sometimes get a good paint job without colorsanding, but to make it look glass smooth, you have to sand. I have looked closely at some new car paint jobs and even they have some orange peel to them.

Here's why I always color sand...
This is what my tank looked like after the last shot of clear-coat..



Not too shabby...it looks purdy and shiney.. ...has a nice gloss to it



THIS is after color sanding and buffing...


Like raven said...why spend all the time and work painting to get a finished job that 'looks pretty good', when you can do just a little more work and have one that is outstanding ....

Perhaps I'm just easy pleased.

 

Re: here's a nice how - to spray bomb paint job w/ good resu

It's all a matter of preference... I tend to be a perfectionist because I know there's some wanker out there like me, who looks at a paint job and tries to find the imperfections...lolol 8) :lol:
