The crossbars on my 2010 AI are looking very ordinary. To be honest they started loosing paint from day one. The finish on my 2015 AI seems far more durable. In any case I have removed them to ensure there wasn't any significant corrosion. There was a little white powder near the bolts but otherwise they are in pretty good shape. Whatever paint was used in 2010 is coming off very easily. The question I have is what paint should I use to ensure a longer lasting finish this time. |

I've used Rust-oleum https://www.amazon.com/Rust-Oleum-7779830-Stops-Spray-12-Ounce/dp/B0009XCJWU/ref=sr_1_4?s=hi&ie=UTF8&qid=1483010697&sr=1-4&keywords=rust-oleum+spray+paint Black, of course. Seemed to work fine, but I've sold the boat so I don't know how it is now. Keith |

You might want to consider having them powder coated. That would provide a much tougher and better coating than paint. Powder coating is often available locally for reasonable prices. Or, if you have the right equipment you can do it yourself. I invested in about $250 worth of powder coating equipment which has given me the ability to coat many things that normally would be painted. It was well worth the investment and the results are incredible. Powder coating is very easy to do, no skills are required. |

Sure: Here is the powder coat dual voltage gun I own, currently on a sale at a very low price of $110: http://www.eastwood.com/dual-voltage-hotcoat-powder-gun.html This gun is all you need for most jobs and works perfectly. From there order any color powder you want: http://www.eastwood.com/hotcoat-powder-coating/powders.html The choice of colors and finishes is amazing. You can even do chrome and metallic like finishes. If you don't already own an air compressor all you need is a very small inexpensive one costing about $50: https://www.amazon.com/Campbell-Hausfeld-Compressor-1-Gallon-FP2028/dp/B000BOCBAM/ref=sr_1_1?ie=UTF8&qid=1483068544&sr=8-1&keywords=small+air+compressor Even this one is overkill, you only need 5-10 psi at a very low CFM, basically only a small puff of air. That leaves only an oven. Many people simply use an old toaster oven. Even a new toaster oven will only set you back about $60 or so: https://www.amazon.com/Hamilton-Beach-31105HB-Countertop-Silver/dp/B00M39MPP4/ref=sr_1_18?ie=UTF8&qid=1483070892&sr=8-18&keywords=extra+large+convection+toaster+oven or this one, specifically designed for powder coating on sale now for $90: http://www.eastwood.com/eastwood-bench-top-powder-coating-oven.html If you want to do even larger items you can buy a used kitchen oven at an appliance recycle store for next to nothing. Or check Craigslist, many people offer them for free if you'll haul it away. I found a restaurant bakery oven use to make muffins on Craigslist for free. If you want to do very large items you can make your own oven out of sheet metal, some insulation, and a heater and controller. There are many plans available online. The parts cost around $100- $300. Some are even designed to fold up or come apart for storage. Basically anything that will heat up a part to 440 degrees F will do but please don't even think about using your kitchen oven you use for cooking, not if you value your marriage. For extremely large items that can't fit inside an oven like a chassis, people use infrared lamps. Powder coating is remarkably easy, and takes no special skills. All you do is prepare the surface by stripping off the old paint either with abrasives or chemical strippers (actually with the dual voltage gun on high power I've even cheated by spraying over the existing paint or powder coat). Once the surface is prepared you connect a wire to the item which then gives it an electrical charge. You then spray the dry powder onto the item which is attracted and held by the charge. You then place the item in the oven for 20 minutes at 440 degrees F which melts the powder. After you remove it from the oven and allow it to cool, it's perfectly coated with a material tougher than most paints and ready to use. You can even apply a second coat. It's not a solution for everything, it only works on metal items, not plastic or wood, but for that application it's great. I've made far more money than I paid for all the equipment simply by doing small jobs for friends and acquaintances or letting them use my setup for a small fee. It can be a real money maker if you ever did real jobs for people. |

I've had the best luck painting aluminum when I put a thin coat of rustolium aluminum primer down first (self etching), then top coat with a harder than normal paint (like automotive paint (duplicolor). I always finish everything out with a coat or two of clear coat (UV protecting, I use Krylon). Actually when my 2012 TI was brand new, before taking it out the first time I clear coated all the metal on my TI. I soaked all the aluminum rivets,stainless bolt heads, and any joints (aka knuckle joints) to prevent water wicking. I then took black 3m electrical tape (only use 3m tape not the cheap stuff) and wrapped all my AKA bars with electrical tape (like you would wrap bicycle handle bars). It's now 4 yrs later and everything still looks like new. We use our boat weekly in salt water. Seemed to work nicely for us, and if I ever get a new TI (my fourth), I will do exactly the same. FE Edit: The electrical tape prevents the AKA bars from getting all scratched up when I throw them in the back of the truck (lol, I'm not a delicate person, no kid gloves here). |

That is exactly what I did. This is my 3rd edit. I'll get it right yet. I used Moeller Zinc Chromate as the primer. Available on Amazon: https://www.amazon.com/MOELLER-MFG-COMPANY-INC-CHROMATE/dp/B000N8LR24/ref=sr_1_1?s=automotive&ie=UTF8&qid=1483144284&sr=1-1&keywords=moeller+zinc+chromate+primer Although I have several spray cans of paint I might have used, I'm sure the finish black coat was Moeller Mercury Phantom Black Engine Paint. Can't seem to find that on Amazon, rather they are now showing Moeller Marine Mercury Engine Paint, https://www.amazon.com/Moeller-Mercury-Engine-Spray-Paint/dp/B001HWX9KI/ref=sr_1_cc_1?s=aps&ie=UTF8&qid=1483144553&sr=1-1-catcorr&keywords=moeller+Engine+paint+mercury+phantom+black I also used a wire brush & wire brush wheel on my drill plus sanding down to the aluminum.

Bob, I edited my previous post to provide the particulars on the primer and paint used. In fact, I have a can or 2 of the Zinc Chromate primer. I could bring one down when we get together on Jan 13th if you can use it. Keith |
