Sprayers

Billy's doing a beautiful job on his Catalina project! I'm wondering about the type of sprayer to use on mine.

I'm going with Easypoxy (one-part). Best I've found is it's safe(ish) to spray. Any advice there?

I have an airless, but not too hip on that.

Any advice on the standard spray set-up? Can borrow a sprayer, have the compressor.

How about the HVLP type. Much less blow-by/over spray I'm told.

Whatcha think fellas?

Thanks!

Hi Mark I would say to use a HVLP hand held like a body shop uses and you are still going to have some over spray so build a tent so neighbors cars don't have spots on them.

Thanks Mark!

HVLP for sure. Once you decide on what type of paint, it should have instructions on spraying, specifically what size tip to use. Once you know that then you can look at the gun, which will tell you what kinda air supply is needed and then make sure your compressor and set up is going to supply the right amount of air flow. The psi can be meaningless if the flow isn't there!

There's lotsa info on the web about spraying, but it boils down to having enough air flow to the gun. The gun I got at an auto paint shop is a Finex FX3000. It's good for primer, base, and clear finish and a good beginner gun that I can get multiple tips for.

The safety factor is huge when spraying. Many of these paints are very toxic and flammable, scary stuff. The less toxic stuff all reccomends a good respirator and filters. Even if rolling and tipping you should have the right safety stuff to protect your lungs, gray matter, liver, skin, and kidneys from the toxic vapors in some paints.

The safety side of the System Three products (http://www.systemthree.com/ ) is what sold me on them. From there site for the primer "Carcinogenicity: This product and its components are not listed as carcinogens by OSHA, NTP, or IARC" and for the top coat it is the same. There water based so you don't need toxic stuff to clean up with also. OK, I did use some acetone, but just a bit after water and hose with a spray gun had cleaned everything else off and flushed through the paint cup. It was cool!

IMHO,
I have painted a lot of motorcycles and tanks, definately go HVLP, and do yourself a favor get two sizes, Regular and detail. Then practice.
If you need anything to practice on I have a large barn, you can spray till you hearts content. :wink:

But seriously, a good practice technique (this works with tip and roll also) is to practice on a piece of glass. If you can get it nice on that you can paint on anything.
Keep us updated.
