Just bought 2 gal of PPG Concept AU (over 3 gal when mixed) Toyota

(white)...........................$1032.00 The control surfaces on the
DG-300 I'm rebuilding have been stripped, filled, sanded with 80g
followed be 220 dry and look good to go for painting. I use a 4 power
magnifying glass with a drop lite to spot anything I missed (old
eyes). The 80 grit scratches will disappear on the second coat and
will insure a good "tooth" is given to the paint which is important
anywhere you will be taping (wing roots).

One thing that hasen't been mentioned is a good water trap. All
compressors produce water and it must be trapped or your paint job
will be pock-marked with thousands of little craters caused when water
droplets form on the spray nozzle. I use a toilet-paper water trap and
it does the job, just replace the roll before each new
job...........................you can even dry out the old filter and
use it for its origional purpose!
Cheep-o, JJ


JJ,

What do you use to build up after removing the old gelcoat?

Why AU versus PU?
