Hi , can i use phosphoric acid in my oval gas tank ? I have one gallon. Do I need to dilute it and how long should i leave it sit ? I think i should be rotating it every 24 hours. I will appreciate any information. Thank you Jim T.
I had great results using muriatic acid an gravel on two 30's Allis Chalmers I did for a friend... Obviously you need to be on point when doing, Poured it in with clean gravel, Rolled around/back forth.. Didn't take long.. Then empty, I rinsed with water an lil soda, Then splashed some diesel fuel in to keep it from rusting, While getting ready for paint. 16 yrs. Later never a problem
The phosphoric acid will work fine ..... just the idiot post that shows you have no idea what you are doing ...... Hope someone can help you.
I've used it full strength and just keep rotating to get all the areas. I use home depots prep and etch its like $17.00 a gallon by me. After its clean I've used the kbs coatings tank seal kit and it worked great.
