I've been exploring methods to renovate the interior and trunk body (interior) to clean it up and then apply some type of coating that provides preservation, water protection and maybe some sound deadening while I'm at it. The carpet has gotten pretty soaked when driving in rain so assume there are seams that need sealing or coating. I've looked at Flex-Seal and Ames Iron Coat; but reviews on the first are mixed for common applications. I'm sure there are many more products...looking for anyone who may have done this type of work for any suggestions, products they used, liked, etc. Thanks.
