Paul, With the MTK you don't have to be that nervous about runs. If you get one or more, just wait a day or so, sand the run down (better yet, use a run file), then sand lightly all over that part with 400 grit or a maroon Scotch-Brite pad and shoot it again. Works slick. To minimize the possibility of runs, try to keep a constant gun distance and keep moving. Lingering for a bit in one spot will almost guarantee a run as will inadvertently getting too close with the gun. Also wait about 10 minutes between coats. CNKS and I had a recent discussion on the procedural aspects of doing a tractor hood. It's in this thread. You might want to review that. You do not want to make a lot of light passes. Each pass should be overlapped by about 50% of the fan width. Three total coats should be more than enough. I usually apply a medium coat for each of the three, including the first one. I know that "medium coat" is not very descriptive. You have to actually do it to get a feel for it. You don't have to have complete coverage on the first coat - e.g. you might be able to see a little primer still showing through it. But it shouldn't be a lot. Don't get passes mixed up with coats. Passes are done continuously (with a 50% overlap) until the part is covered with the first coat. Passes are not done on top of each other, except for the 50% overlap. The waiting time is between coats, not betwen passes. The second coat starts the process all over again after the flash waiting period, which for MTK is about 10 minutes. In your hood case, I'd start in the middle of the top from one side, go back and forth the length of the hood (overlapping each pass 50%) and proceed down the bottom of that side. Then immediately go over to the other side and starting in the middle of the top again, overlap 50% of a fan width to the previous paint and proceed the same as before except down the side you are now on. Tractor hoods are usually not as wide as car hoods so you likely can reach far enough to cover the entire top from one side and then just finish up the side that you can't reach when you go around. Your choice. It should work fine either way. Rod
