For me it was just easier. About 6 years ago I covered the gaps in some paneling with drywall mud to smooth it out then just painted over the whole thing. Has held up and looked fine since.

Think globally act locally. It's easy to look at a news story of a far off place and say I would totally help them! Well that's great that you have a desire to help because there are neglected seniors, foster kids without homes and abused young folks of all kinds who could use a big brother/sister right where you are right now that would be thrilled with your help and require a lot less red tape. Start there!
