Neptune's years are 164.8 Earth years. Its days are 16 hours and 6.7 minutes long. Although Neptune's days are shorter than our days, its years are still longer than ours.
Most colorants will last in your pond approximately 30 days. You may have to add more pond dye before 30 days if you have execissive rainfall, run-off, a heavy out flow, or evaporation. If your colorant is fading you will visually be able to tell and should add more dye to the water.
#5. Re: how long will gel coat last. Yes, as long as you do not leave the boat in the water for extended periods of time (a week or better), and do not leave it in the sun for extended periods of time (a month or better), keep it waxed, gel will last forever.The bad thing about clear gel, is it lacks U.V. protection like colored gels.es, as long as you do not leave the boat in the water for extended periods of time (a week or better), and do not leave it in the sun for extended periods of time (a month or better), keep it waxed, gel will last forever.
