Air diffuser struts rusted right after first ride in rain; That was 2 days after installation. On the third day I noticed rust. This product is not available in orange so I had to sand and paint it. My modifications had nothing to do with nuts and bolts. I pulled out the barrel sleeve and machined it separately. So no one can say I caused the rust. Disappointed. It will cost me TIME because I have to replace rusty products. It costs me more MONEY in terms of other products, I need to change sleeve color because no other company offer this color. I need to buy more sandpaper, primer, paint and varnish. SMX.
