Petseal removal, or not... once again, sorry

Hi all,

sorry to drag this up again, although it is a slightly different question, I have a steel tank which was Petsealed 20-odd years ago and has never had bio-fuel near it, the petseal worked really well with 4* and LRP, and is bone hard, the tank is snuff dry and clean. I know the petseal will be dissolved by ethanol, when I use the tank again, but do I have to remove it?, or could I just seal it in with a new generation sealant?

I know I could strip it out with Caustic Soda Liquor, but it would also dissolve my original 1960s aluminium Monza cap, and definitely the very nice two--tone paint job which took me months of filling, painting, curing, cutting-back, painting, cutting-back etc, so I'd just as soon not, if it isn't necessary, (the last time I cleaned a tank out with 32% Sodium Hydroxide, it got so hot the paint bubbled off, although its brilliant for iron heads etc), any thoughts, anyone?

Cheers,

Niall

Hello I clean my tank with this new Paint striper it works really good but you have too leave in for a time, like 3 hours or so just keep coming back every so often to see how its doing, But I do not know if it will work ok with alloy tanks, You can only try out a small patch first Yours Anna J

Niall,

Don't do it! There is still plenty of Ethanol free petrol about, use it or lose it. BP Ultimate is E0, apart from in the South West and so is Murco Super, where supplied from their own refinery. Also there are smaller outlets, such as Northern Energy near Harrogate who supply BS7070 E0 unleaded. What we do need is a directory of where E0 can be purchased instead of the dogs dinner we currently have and the need to contact suppliers at regular intervals. Chris Blake at Murco has been especially helpful. And Anna, you might be pleased to know that even the Beverley Murco 95 RON will be E0 until 1st October 13.

The Petsealed tank on my 16H has only been run on E0 fuel, mostly leaded until recently but always E0 and there are no issues. However, both my ES2 and Model 50 suffered Ethanol attacks in 2007/2008 when this agent was introduced by stealth. I even re coated the Model 50 tank because even the Petseal boss at Autocycle Engineering didn't know about Ethanol. I managed to take most of the Petseal out with long pliers while it was still soft due to the contamination. These tanks are now uncoated as I only coated them for protection but always run on E0.

OK, that's what I do know. What I don't know for certain is if the Millers anti Ethanol concoction will protect your Petseal if you added it to contaminated petrol? You could ask them. Also, I don't know if Sloshwill seal on top of Petseal. Again, you could ask your Millers agent or Slosh directly. I have use the one pack Slosh in my fated 650ss tank, just in case Ethanol is pushed 100% onto us, despite no Global warming for 17 years.Some suggest a drop of 2 stroke oil will help against the corrosive effects of Ethanol, though I'm not there yet as I don't use Ethanol in my fuel. (A highly subsidised scam)

Hope you have complained about Ethanol damage, even potential to your MP.

Neil.

Hello Well the 1960/1Norton Manxman 650, was Built for the USA And was made so they can run on Ethanol with no bother , Yours Anna J

Try the Caswell Europe website. Caswell is a 2-pack epoxy, ethanol-proof. The removal of petseal or slosh is the important first step, using methylene chloride. Been there, done that, but the chances are that you'll damage the paint job unless you're extremely careful.

Why would you want to remove Slosh, Tom? It is Ethanol proof.
