It has been a few weeks since I have been able to do any work on the truck due to my wife's illness. It gave me time to think as well as reflect on the progress that I have made. And even though the ultra-smooth rollers laid down a good 2-3 coats of paint (Smooth Black Durabak), I was not thrilled with streaks the rollers left after the panels had dried. On Sunday I decided it was a worhty investment to purchase a spray gun capable of spraying heavy materials such as Durabak. At $45 it was the best investment you could ever make when doing a project like this. Upon purchase...I dreamed of MANY ways to use this gun and make it an even better investment. If you plan on a Durabak finish like this HIGHLY recomend this purchase...it will save you so much time in the end!
The Gun:
Review the specifications on the packaging in this picture (PSI, CFM, Etc.)
It is recommended by the Durabak Company that you use a gun capable of spraying heavy materials. Should be sprayed at between 45-65 psi. In specific regard to the smooth Durabak they recommend you also THIN the material 10%. My particular gun came with a 1 Liter capacity cup. On first use, I decided to use only 500 mLs of Durabak. To thin 10% that means adding 50 mLs of Zylene (Zylol) to Durabak to get a total volume of 550 mLs. This left me plenty of room to thin/thicken as needed inside the cup. Many have recommended thinning by the gallon, unfortunatly I had already taken out an unknwon amount out of a fresh gallon. It is helpful to get a measuering cup for the zylene and a measuering cup for the Durabak along with paint sticks.
The Process:
1) Tape off/mask any materials you do not want painted.
2) Be sure to sweep out your painting area thoroughly (I used my compressor air adapter and a broom to clean the garage floor).
3) Hang your plastic and setup your work bench/area.
4) Wet down the area in which you will be painting. I used a mist attachment on the garden hose and sprayed the work bench (very slightly) and the garage floor. This will significantly trap any dust particles kicked up in the spraying process and will do a great job of eliminating them from getting on the materials being painted.
5) Thin your paint material is indicated above.
6) Clean all materials that you plan to paint. I used zylene on a clean shop rag to clean all of the panels (doors, fenders, tailgate, etc).
7) I highly suggest practicing on a piece of cardboard or anything else that you don't care about prior to applying your first coat.
8) Make adjustments to FLOW and PATTERN:
a) Overspray - this is when you have too much pressure (high flow) going through the gun. Decrease flow by making changes at the regulator (on the compressor) or turning the bottom knob on the gun counterclockwise (see below)
b) "Chunky Spray" is casued when there is'nt enough pressure. Again make changes at the regulator or turn the bottom knob clockwise.
c) Test your pattern - this controlled 2 ways: by chaning the "bat wing" you can get a vertical spray or horizontal spray. By adjusting the top knob you change the width of the sporay pattern. Play with these two setting to find what will work best for you and your application.

9) When applying the paint you want the gun to remain 6-9" from the work surface at all times, working back and forth on the material. DO NOT USE AN ARCH MOTION. After an hour of dry time you should be able to apply your second coat.
10) Let everything dry. With 550 mLs of material I was able to apply 2 coats to 4 fenders, 2 doors, 1 hood, 1 visor and 1 tailgate. It goes along way!
Finished Front Fender :
CLEANING:
1) Put a 1/4 cup of zylene in the cup and wipe with a clean shop rag. You may alos choose to turn the cup upside down for an hour to empty the cup out as much as possible prior to cleaning it with zylene.
2) Repeat this process.
3) Please a new round of clean zylene in the gun and spray through the gun onto some cardboard.
4) Use the supplied cleaning brush (at least with mine) and clean the rubber syphon hose.
My next goal is to finish the insides of the doors in the coming week (weather permitting). Then assembly begins.
Keep drooling...unitl next time!
