Thanks for a great product. The installation took me, an 87 year old man about two hours to install inclusive of the cleaning of the old dash, which was full of cracks and pieces ready to fall off of it. I think it turned out quite well, but I should have used more than 6 sandbags on the top next to the vent, as two areas were slightly lifted after I got done. I bought a 50 # bag of play sand, and filled 6 gallon size ZipLock bags with it, and taped them shut to secure them with Duct tape. All things considered, I am very happy with the result. I hated looking at all the cracks. My wife has an 2001 RX300, and her dash is perfect. Thanks for making this. When can I put a dressing on it, or do I need to? Are you aware of any way to get additional silicone under the edge of the vent to secure it better, or whether or not it's necessary? Thank You
