Had some rust in my NAA gas tank and tried to clean it out. However, this time I used a strong acid which I have used to clean tile and it seems this has caused a problem.
I have not used the tank for a few months and I noticed that the rust has returned at a very strong rate. So the question is, what can I use to stop the chem reaction? I am cutting open the tank now and it looks like I will need to clean it well so I can paint on a liner for protection.
So basically, want to stop the development of the rust caused by the acid, and also any suggestions on liner to use once I clean it.
Thank you in advance for your suggestions and advise.
