Hi, A few months ago I had a carpenter come in to build some planters for the garden. He built the carcass but had to leave due to personal reasons. I have now found a new carpenter to finish the job. I've had a look at the carcass that has been built and I can see all the nails have rusted due to the rain over the last few months. Do you think I should ask the new carpenter to remove them and put in new nails or are rusty nails not a problem? I think once the cladding goes on the planters they with hide the rusty nails. Grateful for your views on what to do. Thanks!
