do you have a vehicle to have these put on?, It will not coat the inside, but they can be cleaned up easily. This product is ment for outside usage only. Like I said, I have a pair of heders myself, but I dont feel like unbolting the K member and raising the car up to put them on, take readings, raise it again, take them off, then put them back on wiht the product and then take readings, and if they are of satisfactory to me, then I haveto take them off again and put header wrap on them, and then I will take reading, but I will be done. Im really lookign for someon who has an engine dyno, so you can get right to them, or of a older car, oh say liek a 2nd gen Camaro. I wish I still ahd my 79, you could have three people sit in that engine bay working on it without any issues with room, and I had a set of shorties on it, that were so easy to take off.
