Porous blue plastic tank bubbles the stickers off
Permalink  
 

My 04 blue plastic tank has become completely non-gas (as in vapour, not as in American petrol!) proof, which I think is due to ethanol in fuel these days making the plastic go porous to gas, as detailed on other websites.  The OE stickers bubbled off and new stickers soon followed.  The tank is completely fuel proof, but not gas proof, and it leaks gas equally all over.  I'm kind of struggling to believe I'm the only person with this problem so has anyone come up with a good fix for this?

No chucked them ages ago, but big bubbles coming up from underneath all over them.

Hi,

I've had a set of D&D Graphics decals on my TTR for about 5 years and there are no signs of bubbles.

They have small holes all over them which I believe allows the plastic tank vapours to escape.

A mate told me that the original Decals don't last very long at all so this was the obvious way to go.

They weren't cheap but there were many design options.

Hope this helps

Cheers

Jeff

I can remember plastic stickers bubbling off my new Suzuki Rm100T in 1980. I think all plastic tanks suffer from this issue, the stamped holes in the graphics for plastic tanks seem to be a solution, to help let the petrol vapours escape.

I am thinking of trying this stuff to seal a rusty steel thank..

they also state it can be used on plastic tanks.... may stop the benzine
gas leaching though the plastic...

I looked at several of them, some say OK in plastic, some not. Bit worried I might spend £50+ and then find somewhere down the line that there's some horrible unexpected long term effect. The possibility I'd come up with is that it might set hard and then crack when the tank is biffed on a rock. Was kind of hoping someone might have tried something and be able to report how it worked long term. I tried putting some vinyl on that I'd used a pinwheel to puncture all over first - but it does rather look like vinyl that's been attacked with a pinwheel! I'm quite worried that very long term if I don't do something the plastic will eventually leak fuel or go brittle or something, ie leaching gas is just the first bad symptom and worse is to follow if I do nothing, or just mask it with graphics that are not gas proof!

I used these 6 years ago and they have not bubbled or lifted in anyway. They are nice thick pvc that is perforated.

I reckon that Ballards racing decal could be worth a couple of HP.
