Spray Gun vs Spray Paint - The Debate Thread

High On Octane

Ton Up or Shut Up
I want to start off by saying, I fully anticipate and expect to be criticized for my points of view on this topic. This is not a problem. The number of people who rattle can on this forum is FAR larger than the people who are shooting paint. The purpose of this thread is to discuss and debate the pros and cons of spray painting a job vs shooting a paint job.

Now the general consensus on this forum is "Rattle Can Bling All The Way!" Now I get that not everyone has access to a compressor, paint booth, and paint guns, so spray painting appears to be the best most economic solution. And this, I argue. Some suggest that rattle can is "AS GOOD AS" a regular paint job. This too, I'd like to argue, but not after having a chuckle over the claims. But, I don't want this thread to be about opinions, it should be about cold-hard-field-proven FACTS. And let's keep it friendly, I don't want this to turn into a big argument and pissing match. :)

I'll start this debate by stating that no rattle can paint job can be "as good as" a traditional paint job. The chemical structures are different, have different reactions, different properties and different application procedures. While a properly executed rattle can job can look "as good as" a traditional job, it has been proven in field use that rattle can paint and clear have very poor UV protection, and the lack of activating/hardening agents also makes it prone to lifting and peeling. Granted, technology has greatly increased the usability and durability in spray paints since the 70's and 80's, the fact remains that it is still spray paint.

Now you may be thinking "But spray paint is the only option I have." To that I call bullshit. Where there is a will, there is a way. Now you probably want to call bullshit on me for that statement. So let me show you this:



This is my 1958 Enfield Indian Trailblazer. The bike sat for 25+ years when I found it in a barn. When I got it, I wasn't even working at a body shop at the time. This was restored in my 20' garage, at my apartment complex, NO ventilation, in the middle of the winter. I'm not saying I'm a better person than anyone else, I'm just saying that when you have the will and desire to accomplish something, it can be done. Oh, did I forget to mention I did this paint job with cheap POS Harbor Freight paint guns? Still don't believe me? Look at this:



As you can see, no windows. I opened and closed the garage door to circulate the fresh air while it was snowing outside. Seems insane, but everyone I showed it to thought I spent thousands of dollars on it. So how much DID I spend on this paint job? About $350, and that includes the new paint guns from HF. Yes, I only used those paint guns a few times before replacing them with MAC, DeVillbis and Finex guns. But it doesn't change the fact that I did a "Thousand Dollar Paint Job" with bare minimum everything.

So, I'm eager to know..... What makes your rattle can paint jobs "as good as" my sprayed paint jobs?
 
The problem with your photo is that EVERYTHING in your garage now has an unremovable layer of paint dust on it, for generations to come. ;)

I do agree with you that you absolutely cannot use rattle cans to the level of even a cheap HVLP system can accomplish. For single stage paints, you can get by with rattle cans, and even some 2-stage can look decent, but the control you get from a spray gun is light years away from the plastic button on top of a rattle can. There just is not enough control for all environments. In a pinch, it's fine, but if you want really top shelf paint on your bike, a HVLP setup is key, along with the proper basecoats and clears.

I painted racing helmets for a few years in my garage, and a simple, inexpensive setup can be put together for not a lot of cash. Keeping bugs and dust out of the paint, keeping the paint out of your lungs and off of your skin and making sure you aren't destroying everything else in your paint room are the most important parts of a good home-brew system.

It definitely can be done.

If you want a good inexpensive paint gun setup, look to the Devilbiss Finishline systems. You get a lot for the money, and it's better than the HF guns out there on the market.

All the important stuff was in the front of the garage under masking plastic. The only stuff that got over spray was junk. ;)

And yes, the DeVilbiss Finishline is a great gun for the money. It's what I use to spray sealer before base coat.
 
$350 buys a lot of spray paint tho.....tough to walk out of a paint store spending under $200 even if its just black
 
One could always just have every last piece of a bike powdercoated and have the "best" and/or "longest lasting" finish of all. At some point, you do reach a point of diminishing returns. Personally, if I still own a bike when a rattle can paint job needs re-done, chances are I'd be ready for a change anyway. ;D
 
I spray all of my stuff. I have a paint warehouse a few hours away in Tulsa that sells acrylic enamel for $15 a quart, or a little more for custom colors.
Painted this bike for $60 (quart of Bahama Blue, Silver, and Gloss Black, and $15 shipping), and had plenty of paint left over.

I am quite fond of one rattle can color. It's from Napa, called Iron Cast. Costs about $15 a can. Lays down superbly, and before I had a spray set up, I could spray all my parts, and take them to a local body shop and have them cleared for $75 or so.

Pre-clear:

Rattle can is perfectly fine, if you use a real clear, and not a $4 can from Walmart.
 
Nice J-Rod! That's what I'm talking, a quality sprayed job for dimes that will last years. :)

I only have $25 into this paint job. I already had left over materials from other jobs and only spent money on the gold dry pearl. ;)

 
While I am in agreement with the gun vs can argument being made by original poster... I get stuck on the booth issue. How can an average guy (or gal) spray without a decent booth? I mean.. and not cover everything with overspray? Does anyone have a link to a cheap DIY booth idea or ideas?

I think the big thing with proper gun painting is longevity. Big difference if you want to paint it and know it will last for decades.

HR.
 
You can make a booth on the cheap in your garage. That cheap plastic sheeting they sell at home improvement stores.
 
I painted this with spray paint ....and pinstriped it myself....with touch up paint! ....a regular rembrant i kno....but it only cost me $9.50 including the tank.....

For what its worth on the booth, I used a big box and a few smaller boxes with a little fan on the end to draw fumes out into an hvac filter that caught over spray pretty good... mind you this was just for a tank, side covers and a tail not a big job, and I used a wood rotisserie thing that I drywall screwed a wood rack so I could turn and paint. Not the best but it kept the VOC's out of the shop and dirt off the paint and clear decent. the guns... Harbor Freight 3 pack of purple whatevers still somewhere in a tote and a pancake with drier balls at both ends.

What I would worry about is the whole proper use of materials and disposing of the crap after cleanup, this is where the "can" shines the most.
 
I bought a new LVLP gun and the amount of overspray is less than a rattle can. VERY efficient, insane amount of control, and you don't need a high CFM compressor to run. Lucky for me I have two separate garages at my house, one is a standard 2 car garage, the second one is about 3/4 size garage, and this is where all the messy stuff goes down, eg, grinding, sanding, painting... If you spray any paint with isocyanates indoors you are asking for trouble unless you have a closed air source. I believe the 2k spray paint cans have isocyanates in them as they are urethane. I usually spray urethanes outside, wear a mask with fresh filters and try and stay upwind. You can get good results but the bugs are always an issue, pick them out with a needle, dab of clear, and cut and buff later.
 
I have a nice Devilbliss if anyone wants it. Take $100 with the regulator. I picked up a couple Sata's, and never use it anymore.
 
I use to rattle, now I never look back... I use a tent to paint outdoors.

But I made more mistakes with the gun at the beginning setting me back time.

It certainly take some time and some wasted material getting acclimated with a gun.
