Keeping an ibc clean when used as a water tank

[David.]

What colour is black paint inside the can with the lid on?
Clear tanks degrade and split much more quickly than black ones in sunlight, so black are worth whatever they cost, tbh.

Something like this maybe, Zinnser and Rust oleum seem to make all sorts of paints for awkward jobs.

Does seem to be trend for painting uPvc doors and windows lately, so there is something out there that will stick to plastics.

i was making a joke, actually come to think of it if it was painted black first then white over that it would reflect light/heat better
plastic suitable paint might last longer ?
.
i keep meaning to do some i would use a compressor and blow it over with the gun ,only take 5 mins

I know, I was typing a reply but too tired today to figure out was I being sarcastic or a pansy so I scrapped it (I didn't type "pansy"!)

Got several white tanks here and bought my first black tank this year (€100).
