Note: Read this excellent article to get
you headed in the right direction as you think about painting your RV.
5/17/99; 3.0 hrs; started building paint booth.
I purchased 300' of 3/4" DWV PVC pipe and a box of tees, couplings,
and els. The plan is to build a frame that will be covered with construction plastic. I
intend to pressurize the booth with a fan and exhaust the air out the shop door.
This reminded me of days long ago spent building stuff with Tinker Toys! I
thought some bracing would be necessary since the pipe is kinda floppy; However, all I am
trying to accomplish here is the construction of a tent, and once the plastic was
installed, the whole works stiffened up nicely. Booth size is 12' x 20' x 7'. If this
thing works then hopefully it can be disassembled and used in somebody else's shop.
5/20/99; 3.0 hrs; doing Bondo touchups on fuse and cowl.
5/22/99; 4.25 hrs; working on paint booth.
Four foot two-tube fluorescent light fixtures were jury-rugged to wood
stands and located outside the booth. Good lights are a key to success in painting.
El cheapo 24" box fan is mounted outside booth and sealed to the
plastic with duct tape. Below is the oil-less compressor that will supply air to the
respirator hood. Another fan will be added if deemed necessary for air flow.
(Note: I ended up just leaving the end of the booth open and
letting the paint fog drift into the backyard. The fan did provide some air circulation in
the booth for the gun operator, however. The main purpose of the booth is to protect the
inside of the shop from overspray....it was only partially effective...)
Air conditioner filter is taped into place on inside of booth for fan. I
am pressurizing the booth in an attempt to avoid sucking in junk around the edges of the
booth (especially the bottom).
5/31/99; getting stuff pulled together and finishing up the booth.
Here is the respirator hood borrowed from RV6 builder/painter/pilot
Michael Delashaw. It has a perforated hose in the hood that is connected to the oil-less
compressor. Tear-off shields keep the window from getting painted. The only marking I can
find on the hood is "Survivair, #981801".
This is a water filter that uses a roll of toilet paper for an element. It
is from Motor Guard Corp. (415-838-7777), model M-60. I have been told that I will be
amazed at the amount of water it will collect.
Devilbiss HVLP gun (about $175.00) proved to be a good item for RV4
builder/pilot Mark Spry (Have you figured out yet that I have a tendency to borrow from
builders who have already been through the painting process? This is why you want to
network with as many builders as possible). Compressor needs to be able to supply 23 lbs
at the gun regulator with the trigger held open.
Since my 20-gallon compressor was struggling to maintain the volume needed
for the HVLP gun, and I didn't want to buy a $400 60-gallon unit this close to the end of
the project, I came up with this solution. Three 12-gallon portable tanks were plumbed
together to form a 36-gallon reserve tank. The toilet paper filter is downstream of the
All aluminum surfaces get rubbed down with maroon ScotchBrite pads and
rinsed with water. (Remember when you were so concerned about maintaining the
glossy finish of the aluminum and avoiding rivet set marks??) This is followed by PPG
DX330 Degreaser just prior to shooting the epoxy primer.
