Email Q&A: Repairing Manufactured Holds Question: Can cracked plastic holds be reliably repaired? If so, what glue/bonding agent would you recommend? Thanks! Dave Answer: Dave, it depends on the kind of hold you have and how it cracked. If you have a hold that doesn’t have a sand-type filler and the crack isn’t through the bolt hole, you are doing good (for example I’ve seen pusher and voodoo holds like this). If you do have the crack through the bolt hole, you may end up recracking it after it is repaired because the compression strength of bonding agents such as epoxy or polyester resin (bondo) is usually less than the material the hold is made out of. I can only guess since the manufactured hold I attempted to fix had a sand filler and it just didn’t want to realign well enough, but I’d try using epoxy
