Depends on the primer used; if you go with a "high fill" all-in-one "high
solids"
primer you affectively get about 3-4 layers of standard primer in one
application
and depending on your compressor and spray gun nozzle you can lay it on
really thick and block straight back after 36hours curing; wet on wet with first
run a fast light mist to aid adhesion then back over for full coverage; you
will probably need at least two sessions with primer and maybe a third... I
used All-U-Need on my last project which is a great product; you just can't
leave
it for months though before blocking otherwise it will fully cure and be too
hard to block back easily. It provides a 12hr window to spray another fresh
coat on and it will fully seal off against any moisture absorption 12L will do
the whole aircraft; 8L of body filler is a good start and you will probably
find you need more; 4L of feather fine will probably do you; make sure the
hardner
on each product is still in date... All-U-Need is a base primer/sealer that
you use your fillers over top of while blocking and its fully compatible with
all industrial paint systems. You can finish off with another coat of All-U-Need
and do a final block down and you're ready for top coats. Job will be sealed
against moisture until you do... watch your spray suit and airline don't
drag over the painted surface as you go and have a step ladder on each side to
get height when needed... 8L of top coat might just get you there; buy some
extra
for any future paint repairs... then you got your mixing/measuring containers,
pouring filters, tack rags, solvent rags, wax & grease remover, sanding
discs and strips 120 right through to 2000 grit - and here's the caveat; keep
the surface build (layers) as thin as possible, and under no circumstances ever
let silicone anything near or get onto the prep surface... most of the primer
filler you put on will end up as dust on the floor... calculate how much product
will be needed for each wet session/task and have it setup premixed at room
tempera!
ture rea
dy to refill the spraygun pot as you go; plan your wet sessions really well...
See if Peter still does his Melomotive youtube videos, you'll pick up a lot of
useful practical knowledge and skills there. And use a good quality 3M 6000
series
or better dust mask.
