Mr new home expert. Your miles away with your guess on how its fixed. Its a 100% guarenteed fix with minimum mess and fuss. You can use resiliant bars which are about a 97% fix and far more mess trouble and expense to fix.
The fix is not really for discussion on here in honesty because very few know the fix, if we get the go head from dc to fix yours then will elaberate more into how its fixed. Whats the email of who you been dealing with????
