What does everyone suggest I paint the inside of my fibreglass tank with? I've searched through old threads and it seems 'Gelcoat' is the way to go. These threads were from a few years ago so I'm wondering if this is still the case.

My ex-boat builder husband says: either epoxy resin with a pigment additive colour of your choice that you can get from Adhesive Technologies, or a polyester based Flowcoat. The surface of Gelcoat won't go completely hard unless it's seperated from air, which is usually when it's stuck between a mould and the fibreglass it's being stuck to. If you used Gelcoat to paint on like this, the surface would always be a bit tacky. There are ways around this but probably too complicated for a DIY project.

Another option is to use epoxy based 2 pot marine paint like Allcraft, suitable for being submersed all the time.

Thankyou

am looking forward to the photos when you are underway

Hopefully matildaz been taking photos as the tank progresses so they can put a a series of them.

The Timaru Aquarium Soc. does not belong to the FNZAS.

That would be typical Timaru!! Thought as much when I couldn't see it on the map.

Are there Zones of influence?

You could join CTT and get a mag thru them.

I am still waiting for mine tho :roll:

Anyway yes there is a mag which you could wright an article for on your tank conversion....nothing comes for free M thats what happens to gods ( Privat joke I know sorry to hijack thread)

That'll teach me for not reading the fine print!!

If you send in an article (and it is published) you get a free copy of the magazine

I look forward to seeing it - with pics :bounce: :lol:

I'll see how my photographic skills go! and whether I have the courage to send it in!!

Another idea is the AquaPoxy paint line from Resene. It's typically used to line pools and paint commercial floors but it's bulletproof and non-toxic when cured (24 hours). It sticks to pretty much anything so should be ok on Firbeglass but check with Resene directly. If it sticks to fibreglass it'd be my choice - I've seen 2 minute long burnouts done on workshop floors painted with it and when the car drives off you just sweep the rubber off it.

I think it's sold by a few other coating specialists too, it seems Resene license the name from Aquapoxy in the states.

2 pot paints contain horrible carcinogens and are not suitable to be sprayed in a DIY manner, as you need full body protection and proper respirators that are ducted to the outside air, and many need to be "baked".

2 pot systems are striclty proffessional.

Not true. Aquapoxy is a 2 pot brush on paint. All 2 pot paint can be brushed on it just doesn't look as good as a spray job.

Im a waterproofer by trade. We often use a nuplex product called Aquaguard which is a two pot hydropoxy. It can be applied by brush or roller. Ive heard that once cured it is safe for water tanks, reservoirs etc. so it should be fine for aquariums.
