Inquiry (采购产品): Roof Shingle Rust Hi, I'm hoping you can help me out. I have a five year old house and noticed about six weeks ago that rust was leaking from my chimney pipe onto my gray composite shingles. Can you tell me what products would work to remove this? I would also need info as to how it is applied and if there are any dangers to using the product. Will it remove the paint as it washes down from the roof? I would also need a round guestimate as to how much the product would cost, and if there are any restrictions for use in the state of Oregon. Any help on this matter would really be appreciated. Thank you for your time. PC **** Hidden Message ***** Patti Cardinell OR 97538 USA Company: none E-mail: selmaretreat@msn.com **** Hidden Message ***** selmaretreat@msn.com
