Starting a few of my smaller Cornwall I projects soon. Much of the Velcro on my Cornwall I/Grille's needs to be refreshed. Whats is the best way to go here ? Just carefully and simply re-glue the old stuff ? (In which case which glue is best to use ?), use new Velcro ? (if so, is there a good heavy duty Velcro on Amz to order ?), or is is better to switch to 3M Dual Lock or is this too secure and might damage the grille material when pulling off ? Thanks for any thoughts, advice.
