I have an older aquaplate watertank that is now out of warranty. When I cleaned it out I discovered one floor panel has lots of bubbles erupting (looks like rust erupting) and there seems to be some damage to the polymer coating - a scratch in one spot. The rest of the floor and the walls all look fine. What would be the best way to repair and seal this damage? I've attached a couple of photos. My thinking is that I would have to sand back any rust spots, apply rust converter and then paint over with some sort of sealer. The floor is aquaplated galvanised sheeting (with aquaplate on both sides). Any suggestions would be much appreciated!
There are 2 products that come to mind. The first one is Rust Bullet. From your photos I would say it would be exactly what the doctor ordered to solve your problem.
Just wire brush the loose rust and scrape the blisters. Apply it directly to the rust. No need to sand to bare metal. Apply a second coat after 4 hours.
Since this is a under water application you may want to consider a 3rd coat.Thats all there is to it.
Thanks Doc,
The rustbullet product looks good, but I think it needs to be in contact with the metal to work. The thing about aquaplate is that it has a polymer layer bonded on to it, which may prevent the product working (unless I somehow sanded it off). I guess the same goes with cold galv or other rust converters.
Bags, Call Rust Bullet and ask them. I believe you will find that it will adhere to the polymer layer just fine. Rust Bullet is a special urethane which will adhere with a death grip.
The link above shows product in use for home and farm stuff. Has a nice video to watch to.
I like the automotive silver. It is a bit thinner, brushes & rolls on easy.
A pint is $9.99 A quart $39.99 One gallon 129.99
Call them and tell them how you want to use it.
If you get it on your skin it takes a long time to wear off.
Keep the can lid area free of Rust Bullet or you wont be able to reopen the can the next time you use it.
If you have product left over and you wish to save it, wrap the can in several layers of shrink wrap to keep out all air. Air will turn it rock hard. :laughing:
