Tank sealing

[nige]

Just got another tank for my f2. Inside of the tank is near rust free. My question is would it be worth sealing it before the ethanol f##ks the inside ?
Not sure wether going to respray the tank as got side panels to match,
If I do seal inside what is the chance of cleaning etching and sealing the inside of the tank without nobbling the external paint job.
My existing tank has gone at the seams ( paint turning brown on edges where fuel bleeding through). If the tank is solid may sealing it sort this problem ?

I'm sure I see an additive some where that neutralises the ethanol ?

If its only the seams on your original tank then POR15 should fix it - keeping the pre-cleaner and etcher off the paint on the outside is the problem - can be done though

Por 15 will do it. My tank was mint inside, I had it painted, filled it twice with petrol and noticed the seam was leaking. Had it full of vinegar and diesel for a while to clean it before paint etc. never leaked then. If you are REALLY carefull with Por15 you can seal the tank before or after. Me personally would do it now before paint then you know it's going to be a good clean tank and will not give you any issues again.

Hi,

If the new tank is near rust free I would buy a por 15 kit for your leaking tank. The first 2 stages (clean/etch/neutralize) can be re used so would use these on the good tank to sort the little rust it has but then of course get it leak tested before paint.

I did the por 15 treatment on a tank with some slight surface rust patches. Yes it worked really good and the liner did not lift but then decided on a colour change and as I had by then found a mint tank I tried to sell the other one but no one believes you when you say there were just some light patches and think it was holed so ended up with a pittance for a tank that cost £100 + Por treatment + paint
