Salt water is very good at seeping its way through any coating weak spots and starting corrosion. Obviously the best solution would be to strip and re-coat the entire bracket but if that is not feasible, you can try the following. I have seen powder coating cured with propane tank heaters and the powder has held up so far. These screw on to the top of standard propane tank and are pretty cheap (around $30-$40). I would recommend you also have an infrared thermometer to monitor the temperature of the part while curing it. Thoroughly wash the area with dish soap and hot water, then dry it. Depending on how well you want the final finish to look, you can either cleanly mask off an area close to the hole and live with a raised edge or you can treat it more like an autobody repair and mask off a wide are around the hole, spray the area and cut and buff the newly sprayed powder to try to blend it in. This would look the best but is also the most labor intensive. Enlarge the hole and scuff the powder around the hole and also the edges of the hole. Thoroughly clean the area with denatured alcohol and allow it to evaporate completely. Ground the piece and shoot the powder. Then set up the propane heater and get the area up to the cure temp and then start your timer. Remove the masking after the powder flows out. Closely monitor the temps because the heater is not going to be as consistent as an oven. That's pretty much it. I cannot guarantee this repair as I have not tested it with any marine parts so you should monitor the area to make sure that the powder does not delaminate, and check for any signs of the powder bubbling or flaking due to corrosion. <br /><br />If you don't want to go through all of that to touch it up with powder, the usual fix for touching up boat parts is marine zinc phosphate primer followed by a marine paint. You likely wont be able to get an exact color match though. <br /><br />Hope that helps and good luck with the repair.

Baking the powder coat would not be simple - I would guess the only way would be to use a heat gun, but the risk would be blowing the powder away, unless one could keep the electrostatic charge on while heating. Any comments? Perhaps there would be a better way to seal the aluminum against salt water corrosion?

You will make mistakes and have parts not come out right. That's just apart of powder coating. The important thing is that when you do make a mistake, that you figure out what happened and how to prevent it in the future. As long as you consistently try to improve, you will start to turn out a quality product that keeps getting better. Previous experience spraying paints does not really transfer over to powder coating. However, the prep that goes into painting is very similar to powder coating. Everything has to be immaculately cleaned and prepped before coating. Read through some of the articles on this site. I'm sure the shop will already have their equipment set up and dialed in so you can skip over those parts but focus on the articles that talk about techniques and tips when spraying, masking, cleaning, monitoring temps in the oven, etc. Good luck!

Even though powder coating is very chemical resistant, I would not trust it when constantly exposed to gas containing ethanol. Chances are the powder coating would not lift, but if it did and I have heard of it doing so, it could cause a lot of issues. <br /><br />If you were to powder coat the inside of the gas tank, the paint on the exterior of the tank would most likely be degrated. It is not meant to withstand 400 degree F temps and a bake in the oven could considerably shorten its life or it can immediately yellow and start flaking.

If you are just an at home powder coater, storing it in your air conditioned home is fine. <br /><br />If you take a powder out of storage and it is clumpy, it should either be discarded or fluidized before use. Chunks in the powder will not flow out in the oven and they will be visible in the finish.
