With so many discussions on this site through the years regarding the infamous paint blistering on our nylon gas tanks, I thought I would give an update on the last M2 tank I painted, in 2016. So far, no blistering after 4 years, despite many days ridden and parked in the hot sun, and using ethanol-containing gasoline. (This was after painting a similar tank in 2012 that blistered in 2 years.) I am cautiously optimistic about this one. For reference, I am copying below the steps I took on the later paint job. (Your results may vary.) I'm no expert on the subject; Some of these steps, particularly the long cure times, were taken from suggestions by others on this site: 1) Sanded all of the numerous old paint jobs from the tank, down to the bare nylon everywhere. (I would not recommend chemical stripper here; traces may migrate into the nylon.) 2) Applied plastic adhesion promoter to the cleaned surface, and then applied 2-part PPG epoxy primer. I let it cure for several weeks, then wet-sanded smooth, and applied another coat of the epoxy primer. Let cure several more weeks. 3) Wet-sanded again, then sprayed with PPG Deltron sealer. Let cure for another month. 4) Wet-sand and applied typical basecoat/clearcoat paint job. Again, let cure for another month. 5) Finally, wet-sanded, buffed and applied new decals. Since the process took so long, I started with a second used tank, so my bike was not disabled for the 3 months taken to do this. Good luck.  | ||

Thanks for taking the time to follow up. This is still an unresolved problem with these bikes. Been holding off on a repaint forever. SteveH | ||

In the German XBorg Forum talks same folks how to made a carbon fiber tank cover like the X1 for the small Peanut and Manta tank for the S1S3, M2. Greetings Frank | ||

"In the German XBorg Forum talks same folks how to made a carbon fiber tank cover like the X1 for the small Peanut and Manta tank for the S1S3, M2. " Do you have a link to that forum? I googled but didn't find much | ||

After doing the external blistering repairs I've started to use Caswell coating to seal the inside of the tank. The bubbling is caused by gas/ethanol fumes migrating through the tank material. Hylomar is good stuff as well. It's still a 90 day job. Do not use Kreem or Red coat. | ||

Just a meandering thought...do you experience the blistering/bubbling if the tank is always kept full in storage? Seems a tank full of (liquid)gas would prevent the fumes from being able to find their way through the plastic. |
