Possible solution to bubbling stickers on plastic gas tanks

I’ve been giving this some thought. I was thinking, if you applied a sticker on some color matched tyvek material (color matched to your plastic gas tank), then cut out the tyvek to match the shape of the sticker, then sprayed the tyvek with 3M spray glue, then applied the sticker/tyvek lamination to your tank, the problem of bubbling may be solved. The tyvek is permeable, so gas fumes could pass between the plastic of the tank and the bottom of the sticker, through the tyvek material. I’m going to try this and see how it goes. Any thoughts on this solution?

Only real solution I’ve found is following a two rules. Quality vented decal, and draining all the gas from the tank when done for the day. My 78’ YZ400 build was completed in May 2018, and the decal has not had an issue yet.
Back in 1977 and 78 my YZ factory decals were usually gone in the first 30 days.

I had a small crack in my 83 YZ100 tank that would seep small amounts of fuel. I used the Caswell gas tank sealer, which works very well by the way, and have not had any issues with stickers peeling. Not sure if it is just coincidence, or an unattended benefit of the sealer.

So, I’ve started the experiment tonight. The weather was warm enough, so I’m hopeful. I’ll post results in a week, or two. Photo

So, today is April 11th. 17 days later and still no bubbling. I think it’s working! Photo
