Is plasti dip safe for water contact?
You'll find varying opinions on if it is safe to use in the water. I did plasti-dip 2 1" white pvc threaded caps which I used on the inside to cover holes I didn't want to use. I let it cure a full 7 days as someone recommended in my research. Yes, I realize I could have gotten black pvc threaded caps, but I already had the pasti-dip from back of the tank and the white pvc fittings were much cheaper at local hardware store. :lolspin:
That was 6 months ago and I still haven't had any harmful effects so far. I would think if it was harmful, I would have had losses of fish and corals. I haven't had any in 6 months.
So take that for what it's worth.
