It has now been just over two months since installing the hood weatherstripping and thought I'd give a brief update on its effectiveness. See my post dated 1-22-2011. In a nutshell I am very pleased with the results. It is about 90-95% effective in keeping out the wintery slush and dirt. I have been able to keep the engine area pretty clean without much effort as a result. The best $28 bucks I have spent to date on the Tig .
