Plastic heating oil tank - can it be painted?

[Brinyan]

I have a green plastic oil storage tank (kerosene).
It’s had the sun shine on it for a few years & started to discolour.
There are no cracks in it & it appears in a stable condition, apart from discolouring.
Can anyone recommend a suitable paint (ideally green), that can be applied?
I will replace the tank if that’s the only option.
Thanks

Zinsser allcoat will be OK.

Thanks for the suggestions.

How old is it, you can pick up second hand ones fairly cheap as people switch away from oil heating & get rid.

New ones are shockingly expensive!!

When mine was new I built a shed around it. Weatherboarded with a felted pitched roof.
At the time there were many reports of oil theft, the sunlight degrades the plastic, and they are not pleasant things to look at.
Totally against building regs which say you can't have anything combustable within 2 miles of the tank.
When we had extension works done the council building inspector was stood right next to it which amused me.
The shed is locked and has no windows of course so why would he query it?

A heat gun (or blowtorch, but that may not be a great idea with kerosene!) applied gently can do a great job of recolouring badly faded plastic.

What about Owatrol Polytrol? That works well on plastics, upvc, composites etc.

I've painted things like water barrels and planters made of HDPE with common or garden masonry paint.

Once things have been out in the sun a few years, the surface loses its waxy nature and simple paint sticks surprisingly well.

Anyone who's cleaned up after a painter will know that Dulux weathershield sticks pretty well to surfaces including glass, upvc window frames etc etc etc.

Obviously any traces of oil will hinder most paints!

Wet sanding with a sanding sponge is effective for cleaning, also old fashioned 'Vim' type scouring cleaner.

Anything that keys the surface of the polyethene/polypropylene is going to help paint adhesion.
Giving the tank a rub all over with 360 grit wet & dry (or whatever you've got) on a foam block should do the trick. Following this up with a wipe of isopropyl alcohol will make for an even better job.
