Fillers and Comparisons
Here's some testing information about two homemade fillers.
Homemade Fillers:
o Aeropoxy + micro
o Alphapoxy + micro
DENSITY
Aeropoxy + micro = 3.8 lb/gal*
Alphapoxy + micro = 3.1 lb/gal*
Alphapoxy:
o has the ability to take more micro than the Aeropoxy (3.1
lb/gal final vs.. 3.8 lb/gal)
o 20% lighter (less dense) than the Aeropoxy filler (if
mixed nice and dry).
o mix was lighter, and is just as easy to spread as the
Aeropoxy. With a little alcohol Alphapoxy spreads exactly like
cake frosting.
AlphaPoxy Note:
Mix 2oz of AlphaPoxy, and 10oz (by volume) of micro will easily cover
an area 24x36 inches.
DO NOT MISTAKE "Alphapoxy" for Aeropoxy and use it as a structural
layup!
SANDABILITY
--------------------------------
Homemade fillers sand easily (if you make it nice and dry) after
about a day of curing. Be careful to mix it about the same dryness
each time you're working on a certain area. If you mix one batch too
creamy that spot will be harder to sand than the other filled areas,
and it is easier to get a high spot as you sand.
