I'm getting confused, on what causes the crazing, many people (including myself) believe these are caused by UV rays adding the material, but experts online actually say it's because of mechanical stress of the material.
In my experience, crazing got worse after last year I sealed the bolt holes with sikaflex, but in the very same day I also tightened the bolts, adding to mechanical stress, so can't really separate causes and effects.
If I were to sum up things: plexiglass crazes because of mechanical stress, not because of sun light, so covering it with adhesive
UV layers is pointless, and harmful because contact with plastic will wish things.
To double check : I know many people cover their windows with Sunbrella fabric
when away, that limits uv exposure but does nothing to mechanical stress.
Do they still see crazing after few years?
