1988 Stern stickers

[charlietango]

I have problems keeping the stickers on my 1988 SN 2001. I put approximately 50 hours a year on the boat, the gas vent does not leak and I strip all wax off the gelcoat before applying the stickers. I always buy the stickert from Midwest Correct Craft so I am sure they are the recommended stickers.

Does anyone have any Ideas or help for this problem?

Thank you.
