Tank blisters

[fraserdog]

I wonder if it affects any other triumphs with plastic tanks? My mate has a 2004 Sprint st with over 60k on the clock and nothing on the paintwork on that.It seems only the tanks suffer not the fairings or side panels which all have decals in one form or another which makes me think it is something to do with the petrol.

Oh it's def fuel but what is going on here in the UK is they are starting to put more crap in the petrol(ethanol) they've been doing to the Americans for years.

If you scour the forums there's been allsorts of hassle Ducati have even had to change tanks because they been deforming.

Stick a Bagster on it  out of sight out of mind!!!

I put the premium fuel in mine,v power,bp ultimate etc with the vain hope that these have less ethanol content than regular and might hold off the impending blisters for a while.

Here's one that's completely off the wall;  what if some tanks still contained minute amounts of moisture (not necessarily water, think solvent)  in the plastic when they were initially painted by Triumph and that moisture eventually causes the bubbles.......

My Steamer has them,and my friend has noticed them on his 2007 Guzzi after a cold,damp spell in his garage. A local resprayer says it is trapped moisture from factory painting.

from another board I got wind of a product that seem to claim to stop issues with alcohol on tanks

In the topic some said they liked the POR15 tank sealers better but they were not discussing issues with ethanol.   Does POR15 say  they are compliant with ethanol? With plastic tanks?

Could see why a sealant might work if it will stick the plastic tank.  The alcohols would not make contact with the plastic so expansion should stop... maybe reverse???  but that might cause sealant to bow, peal, crack??

Well my tank is covered in blisters, impressively covered.
02 Green with black stripes. Some on the stripes have been the full width of them :)

I used Petseal on an old gpz900 tank years ago that had internal rust issues,it cured the problem but while it was curing the tank got so hot you couldn't bear your hand on it,i'm not sure what that sort of heat would do to a plastic tank although perhaps the formula might have changed since then.
