Allum. Lithoplate adhesion question
I am building a 1/3 scale sopwith pup and purchased some Allum. Lithoplate from a local printer. When I purchased them the printer used a solution to clean the plates of there film. When he finished, the sheets still have a dull primer finish on them.
So I tried using some sand paper and they cleaned up to a normal allum. finish. (although they have swirl marks on them)
My Question is: do I need to clean this dull finish off of the sheets back side in order to get a good adhesion to the wood? If so is there a better way then using sand paper? I tried mother allum. polish and it does not work.
I plan to use 3m super77 spray adhesive.
Is that the best way?
Please help. In the garage right now scratching my head?
Thank you for the help!!!
