Update - the 3M 950-300 transfer tape with adhesive promoter on the covers only started to fail under headlight / moderate sun heat. To be fair, this use of that particular xfer tape was at the limits of its specification. I’ve ordered some 3M F9469PC VHB xfer tape which uses the high performance 3M 100MP acrylic adhesive which has a much broader operating temperature range.

I’m going try the new adhesive without adhesive promoter on the lenses because I want to avoid permanent lens damage. It does not look as if I’m going to be able to remove the 300LSE adhesive from the covers. Hopefully it will bond to the 9469 ok. I’ll run some tests before I remount the covers.

I’ll post an update here as soon as I have additional info.
