yes, VHB will hold a lot of weight. I've used it quite often to attach items.
However, there is one very important step that isn't often listed on the tape package if you want the very best possible adhesion. 3M VHB is designed to be used with a 3M adhesion promotor on almost all materials to achieve the holding strength the advertize. this adhesion promotor comes in small foil packages like the small alcohol wipes. It is used on both surfaces before attaching the item.
Good news is it is available on amazon. look for 3m PN 06396 usually available as bulk or individual items.
Using the adhesion promoter I have never had a bond failure. And the few times I wanted to remove something, well, kinda like using red loctite!! a real PITA to get it off, it takes some serious work.
