: Ok my dimples are about 8 inches across and lifting less than 1/4 inch seen
: from the inside of the hull. It is not delaminating. I had fretted about
: my ply not being perfectly flat. People said that I should not worry. This
: is my first foray into the world of ply. Well I would like to fix this.
: Any tips?

i don't think the weighted glass will help. it'll likely spring back. but put a scrap of glass on the i/s 1st to see if that helps, then glass the outside then do the following if no go:
so to change the shape what about adding a 12" long 3/4" x1/4" pc of scrap on the flat on the i/s where it doesn't matter and who's to know. run it right across the area extending into the flats ea side. white glue one in to see if actually works while the clamp from the outside.

if you can acceptably change the shape by pressing this/ll prob be ok. otherwise slitting might be the very last resort.

thoughts anyway,
