Hi All
Am thinking of cutting much larger holes in the tops of the two water tanks for better access and then having them hot zinc sprayed inside as corrosion protection but understand they will still need painting inside afterwards as the zinc coating is still a bit porous. I am not keen on POR15 (trying to get it evenly coated inside as the tanks are too heavy to keep rotating) or Isoflex (which I used on my 4" Burrell). Or is another option to cut bigger holes and then brush on POR15?
Has anybody else gone down this route - cutting bigger holes or zinc spraying and can offer me any advice?
Thanks,
Simon

How about galvanising the whole tank?

I thought the tanks were stainless.

Why bother ?

Tanks are seam welded so no leaks to seal unlike a flanged and riveted tender. Surely they should last a year or two,and then maybe replace with stainless.
Iíve not painted mine and I know of †more than one truck thatís running around with no coating on the inside of †their tanks.


Another option if you want to go down the coating route is google paints for water tanks as on narrow boats etc.

As the saying goes ďFood for thought ď Very Happy

Hi
Iím going to cut inspection hatches in the top of mine and then give the inside of the tanks 3 coats of Apexier no 3 which in my opinion is the best paint to use as itís suitable for salt water! We have used it before with good results!

Hi All
Thanks for the replies, but after much research have decided to coat inside of water tanks with Apexior No 3 paint which is very expensive but seems to be the ideal product.
Have ordered a 2.5 litre can but think I will only need to use a fraction of that so if anybody is wanting to share a can please let me know.
Thanks,
Simon

Hi Simon

I tried apexior No3 on my 4.5 foden and it has mixed results after 2 years untouched my lower tank the upper half was still coated well but the lower half had all gone and the tank is heavily rusted and started to corrode in one or two places, Im not trialing a Isoflex rubber product on them as ive heard its really good stuff and more durable
