We have an older horse barn that has a corrigated galvanized steel roof on it. The roof is about 100 x 40 feet in size. While the roof itself is in generally good repair, we have a trememdous problems with the noise of rain and/or hail on the roof. The horses that are stabled there go crazy during even the lightest rainstorm as the noise is so load you cannot hear a person standing next to you talking. We actually have to turn the horses out during rain rather than have them climbing the walls. I am posting this message to find out if there is any kind of thick paint and/or rubber coating that can be applied to create a sound barrier on the metal. I inderstand that not all noise can be elimiated but need to "turn it down" a little!!! Any advice or alternatives would be appreciated. P.S. - Due to financial concerns, we cannot afford to re-roof such a large area with shingles etc!!

Maybe I'm not an expert as this is a new term for me. Possibly you may be talking about the clear acrylic coated Galvalume sheets that are available.
This caoting was designed to elliminate the "oiled" coating that was used on bare Galvalume to stop it from staining during manufacture and installation from oils. The coating is designed to disipate after exp[osed to the ellements over a period allowing your Galvalume roof to weather naturally. This product has a proven performance record and will provide many years of protection.
Although this surface is able to accept paint quite readily provided it is formulated correctly to bite in correctly you will find it difficult to find a post applied paint system that is economical and that will perfom. Roof exposures are the most extreme. If you want paint then buy a pre-finished metal roof but ensure you investigate and get the high performance coatings designed for roof exposures.

I have heard of "paint grip" before in reference to some roof flashings and things but I have not before known anyone to be making roofing with it.
I have always thought that "paint grip" is a low cost / low quality primer coat that is designed to make an air-drying paint adhere well to the metal.
I do not know this for a fact but I would expect the paint grip coating to wear thin and discolor in a relatively short period of time.
You are quite possibly safe, though, to wiat until the color change and overall degradation of the paint become objectionable and then go ahead and paint the roofing.
