Hi. What brand of paint stripper to remove old sealant from my tank. Heard Nitromorse is not very good now. Don,t know if it make sense to buy a new tankk with cost of repair for remover and sealant.

Sounds like you're talking about the inside of the tank. Nitromors, or any other paint stripper won't work. The old sealant will be hard and brittle and needs to be broken up. Most people put a handful of old nuts and bolts in the tank and shake it for all they're worth. Hopefully that will do the trick and you just tip the lot out.

No I recently used (or rather tried to use nitromors) for something else it is nothing like it used to be you could try caustic soda but I'd be inclined to get another tank.

Another tank is the best option, but it might be worth asking a local paint stripper place - the ones that dip it and use chemicals you don't want to go near. I had my panels stripped and it saved hours/days/weeks.

Tankcare Products supply a Petseal remover. It does work. Neither caustic soda nor hydrochloric acid will.

Thanks for help. Petseal is breaking away like chunks of hard toffee. Not good !

Can you tap it on the outside with a hammer until it all falls off?

I've tried cleaning the inside of a standard rusty tank with paint stripper, nuts and bolts and a whole lot of shaking. Although I managed to remove a fair bit of rust, flakes and gunk, I ended up having to buy another tank and seal that. Seemed to be a false economy to try to sort the old tank out and really wasn't working very well.

Cleaning a tank is pretty straightforward and cheap, albeit that you have to be very careful with caustic soda and spirit of salts. However, removing petseal is not the same process.

Trust me, the Petseal remover does work and will save another perfectly serviceable tank being tossed into the corner of the shed
