I always see negative comments about POR 15. I'll add my thoughts. I've done 4 tanks with POR15, and my current one on my SS was done about 5 or 6 years ago. I've had no problems with rust. It was properly cleaned out and dried, which is key, as any moisture trapped will cause rust. The same company does a sealant which can be used to seal holes, although maybe not as big as yours. I personally like the tank sealer, gives a longevity to these tanks, as they are indeed getting rare and expensive. But that's just my opinion. Clearly not everyone has had positive experience with sealers
The tank is on, fuelled up, and the belts are done. I left the fuel sensor that came with the new tank in, and the once permanent light I had has gone off—it only took 4 years to solve. https://tapvolt-personal.s3-eu-west-2.amazonaws.com/ducati/tank/IMG_0737.MOV
I have also used it on several tanks and had no problems with it at all, the key is in the prep. It’s a great product. I think the reason the op has had a problem with their tank is the fact that someone repaired the hole with fibreglass before putting Por15 over it. It’s the fibreglass that has failed.
each to their own, I totally understand people choosing this course, particularly if they don't weld.
Which of these is the bag for my tank: 1. https://www.ebay.co.uk/itm/19715852...D1RM6N&hash=item2de79065dd:g:RCcAAeSwsVNn5~As or 2. https://www.ebay.co.uk/itm/19715874...X729B4&hash=item2de793ba6e:g:8hEAAeSwGodn6Agq I think #1. #2 looks like it is for the ie model of tank (1999+)
Gurth I think the first one is just a cover that has eyes on it so the second one can strap down to it. So you may need both. The descriptions are AI rubbish.
#1 looks as if it has something missing yes, #2 looks like an entire tank bag. I'll probably end up bidding on both and try and make something good. Looking at the manufacturer site, #2 looks to be a bag for a 748 tank https://bagsterworld.de/pi.php/en/Tank-covers/DUCATI/tankschutzhaube-ducati-748sp.html
Gurth has very kindly passed on to me his original tank so I can try to save it. I won't be able to get into the project properly for a couple of weeks, but when it turned up I couldn't help but get my hand in there and start picking at a couple of loose bits of the badly applied lining material. And of course we all know how addictive picking at something is once you've started. Some of the liner was in there about 1/2in thick, and some was just a thin layer. In the corner with the rusted through holes it was covering a fibreglass patch applied to the inside. The good thing, to help me now at least, is that the fibreglass and liner had been applied over the rust and it hadn't really stuck properly at all. So an hour with a small screwdriver had it peeling off the inside in large patches and lumps. Judging by the 'aero' like make up of the thicker sections it must have been fizzing away really well as it went off when it was originally applied, and no doubt got quite hot too.
Bonus is the tank'll hold more once done. You've obviously got plenty of time, as you will know a pinhole is never just a pinhole. The chassis on my old Landrover had a small hole in one part underneath but it turned out to be so much more as, like a fuel tank they rot from the inside out. Good luck.
