She looks great and will fly better, love that SU 😍
ive always used water based Acrylic with brushes or airbrush, can’t comment on mineral.
ive also never weighed it to see the weight added🧐
once she’s built, pimped out in paint shop, it’s a race to the sky

I will second that.
... I've always used acrylic paint. The cheap little 2 oz bottles you get in the hobby section at most any department store. A couple bottles will cover a plane nicely with paint left over.
Fly like your mad at it.

sometimes I water down the paint slightly for smoother quick coverage, 
as with the euro fighter picture  ED3B15E9-9D30-4B8B-927A-2FC11DDD17F5.jpeg 

sometimes I water down PVA glue 50/50 for final coat once paint has dried and it gives it a glossy shine 😍
and seals the paint

If your that bothered about a little paint sidewayskiwi just use 5mm depron instead of 6 mm, job done you can lather the paint on.
To be honest I just use the same as the guys above my reply and don't notice any difference in weight once painted, I'm sure it will be a couple of grammes but not something that is going to make a noticeable difference, however I do try not to put hot glue along every seam as that does add serious weight ðŸ˜–

it was a genuine question
got to thinking which is better/lighter etc 
Normally use Rustoleum but theyve change the formula , some colours eat their other colours ( black and orange for example) 
Lost a big build to paint eating into the foam (it wouldnt stop either you could hear it reacting) , so once last of spray cans gone will be looking at other ways to splash a  it of colour

With respect to weight it really depends on the quality of the pigments and how many coats you need to cover.  Overall the mineral based paints will likely be heavier due to the binders.  Like shadeyB I use water based acrylics almost exclusively these days, except for using Minwax Oil Based Polyurethane for coating foam board to waterproof it prior to painting.  One of my favorite paints is Createx but at $5.00 a bottle I only use it occasionally.  I generally use department store craft paint and at 0.50 cents a bottle it works great.  In the US, Walmart brand Apple Barrel and FolkArt paints work well thinned with distilled water.  Give them a try, you wont ever go back to mineral based spray cans...

Water based craft paints: 
- Inexpensive
- Doesn't eat foam
- Water cleanup
- Apply with a brush or airbrush
- Spray indoors no health issues
- Dries quickly
- Easy repairs and touch-up
- Lots of colors and you can mix

Ah Sidewayskiwi, I wasn't doubting your question was real, I don't bother much about a little extra weight , I just add bigger faster motors to compensate, some of my planes glide like a house brick but fly amazing.
I generally put a coat of cheap acrylic varnish on by brush before the paint, that seals it and stops the aerosol propellent eating the foam which I have experienced just like you.
