Apologize for the slow response. Things got a little busy for me.

I got the estimate from the guys to get the pool up and going. They quoted over $14K for parts and labor. $8K of that was in painting expense. I know epoxy paint isn't cheap, but $8K??? We finally got an itemized estimate and as I suspected they are saying a 60'x40'x5' pool required 22x 20 liters of paints. Well, about all I know is what a 2 ltr bottle of soda looks like. So I went to a conversion program and found 20 liters is ~5 gal. So, 22 x 5 gal = 110 gallons of paint. How they came up with that figure I have no clue. From my calculations, I estimate ~ 30 gallons of paint for 2 coats. Am I close to what you estimate?

All the other prices/equipment look about right. After correcting for the paint 'error', looks like ~ $4,800 for parts. The only question I have is they call for two "500 liter filters". Can anyone convert that to something that makes sense?
