PPG basecoat clear coat question

[Troy Newman]

The build up is entirely up to you...The more paint you stick on it the
thicker the ridge. As for 20-40mins....depends on your temps....Also use a
slightly colder reducer and it will help....Unless you are below about
60degs then you are stuck with the DT860. The base coat stuff dries very
quickly....I would say 20mins you will be fine...but test it with your
finger. I usually paint the entire model with Concept white this is a fuel
proof paint like the stuff Tony Stillman sells. It dries for a full
day.....in fairly warm temps 60 degs....then I shoot all my other colors the
next day...Yellow, pink and purple stripes and such....with the model all
white these colors cover quickly and with minimal paint build up. Then I
wait about an hr or so and shoot the clear....I think you can go with the
clear quicker...but I just wait to be safe....The whole plane painted white
with the fuel proof stuff...then a good clear like the 2021 or 2042 keeps
the base coat stuff between fuel proof layers....This helps to eliminate the
paint Cancer from fuel. It can still happen and is the cost of doing the
Base Coat / Clear Coat stuff.

Also the 24hrs to clear thing is not a big deal. This paint is for
cars...its for durable and baked in the sun finishes. To answer the question
yes it sticks better in the 24hrs...but its not totally needed..If you wait
a 3-4 days you should sand and re-shoot the color.

If you want to be safe use the DCC instead of the DBC. The DCC is the
concept stuff that Tony sells as the Radio South paint system. it is very
fuel proof. But its a color a day thing...then lightly sand it all say 1000
grit before the clear...Its very fuel proof. Weighs a little more and
doesn't require a clear all colors are shinny and fuel proof. The DBC or
base coat stuff will dry very dull and will go on very dry in terms of the
paint....

On the Concept stuff I use double the reducer to keep the paint thin...then
I use lots of very thin coats to get coverage...Helps control the
weight....total plane primer fill, and done usually with the stickers under
the paint is only about 4 to 4.5 ozs of paint. Some guys are better and
lighter.....The basecoat stuff is much lighter...I would say 2.5-3ozs of
total weight added.

For reducer on the Base Coat stuff DBC I just use about 1 to 1....I have
learned in the past couple years what the paint is suppose to look like in
terms of consistency....And I just add reducer till it looks like that!

Slightly more dense than Skim milk is a way to describe it. Especially the
white.....I use a wood craft stick and use it to gauge how thick.....dip the
stick into some skim milk...and this will show you the consistency.

Painting is tough business....I'm OK at it....guys like Dave Guerin and
others are great at it....The more you do the better you get. On the clear
don't be afraid to get it wet. I learned that the last time.....

Also painting below 60 degs is really going to make your life
tougher.....the base coats are fine below this temp...but they will take
longer before you can tape them.....the clear is the kicker.....it is the
chemical reaction and needs the temp to cure up....If you don't have the
right temps my suggestion is to wait until a 60 deg day and paint in the
morning allowing it to set at 60degs min for at least a few hours....

I have tried the paint it in the cold and then into the shop for warmer
curing...it just don't work as well.
