High Temp plate (sticker) lifespan?

I am having issues with part adhesion in a couple specific spots on my High Temp plate .This after a few dozen prints which are a repeat print for a functional part which I produce. Things began great and I really like the plate though I’m having issues with it of late. I have done the Dawn dish detergent scrub followed by 91% IPA but still have spots where the print fails.

Overall condition of the sticker is great unlike how quickly the cool plate stickers deteriorate. Does anyone know what the lifespan is that I should expect before needing to replace the sticker? The work fin on my Wham Bam plate so I know that’s not the issue.

Thanks

Use the BL liquid glue. It works great on that plate.

So I was able to use 000 steel wool on the HT sticker to get some more life out of it, another 50 or so hours but ultimately replacing the sticker was the solution. Once the decal got shiny it lost holding ability. The point of the HT plate is to not have to use glue and let the heat hold the part. That also allows for the desired perfect matte finish which you would not achieve if using glue.

I’ve used the BL liquid glue on the engineering plate and it works great with a high shine similar to the WhamBam plate. The paste stick leaves terrible residual on prints so that’s a no-go.
