PETROL TANK LINING - POR 15 - What is your experience after treatment ?

(1/3) > >>

400 Cafe Racer:
Hi Guys,

Hope you are all keeping well.

I am preparing a spare tank for respray, its clean inside and before stored it was washed around with diesel fuel to provide an oily coating inside to preserve it.

It looks clean and solid  inside and I was in two minds just to wash out and use as is. On the other hand with Ethanol now being added into fuels I was considering lining with the POR 15 treatment before any Paintwork is started to avoid damage to the final finish.

I'm interested on your input  :)

Thanks

Dennis

If it's clean inside, why line it?

Dennis, I've just had a tank resprayed for my 400 and the sprayer (who only does tanks etc) said not to use POR or similar as I had a good tank. He said if the tank wasn't that good inside then a sealer would be better - who am I to argue!
I try and use Esso Supreme unleaded when I can and I'm sure that helps things.

Thanks for your reply Matt,

Good to hear the opinion of a tank sprayer.

I do use the Esso Supreme thanks, and last ride before winter I always add a very small amount of engine oil to any petrol in the tank and swish around to leave a layer internally. Like the diesel used or 2 stroke mix, this will help to resist rust formation.

I'm interested to find out also because several members in our VJMC club swear by POR 15, but I feel it could overkill on a clean tank and if the treatment delaminates later it could cause other problems. Manufacurer claims seem to say it is OK up to 10% Ethanol content.

We will see who else replies.

Cheers

Dennis

I use Nurse Julie’s endorsement of the diesel wash on the 550 tank and on the 750 tank I have a Frost ethomix addative See what like in the early spring just to compare. Both tanks in similar condition inside. No tank sealer.
