    78 GS 750 Rebuild

    So the good news is that I was able to sand all the runs back. The bad news is there were air bubbles trapped in the runs and it looks pretty bad. After sanding back the orange peel with 1000 grit, I can see that they're in a couple other areas also. Google tells me it's "solvent pop" which...

    Note to self: It's much quicker and easier to scuff sand and spray more coats of clear if needed than it is to sand runs out of clear...

    So a bit of orange peel, a bit of overspray, and a few nasty runs, but all in all not too bad. 20180916_190100 by samL9, on Flickr You can see the runs on top in this one. 20180916_190206 by samL9, on Flickr 20180916_190154 by samL9, on Flickr Runs on the side 20180916_190122 by samL9, on...

    78 GS 750 Rebuild

    I'll post some pics tomorrow in the daylight. Maybe disaster is a bit of an exaggeration. I definitely have some sanding ahead of me, but it really did come out awesome.

    78 GS 750 Rebuild

    Progress! :triumphant: Color went on nicely. A little hair or something got stuck in one spot. I sanded it out, resprayed, and kept it moving. Then came the disaster of the clear coat. I got 2 guns...one for primer and color, and another for clear. I had the color one dialed in nicely. The...

    78 GS 750 Rebuild

    I was able to take care of the trouble spot. I think I've got it as good as I'm going to get it. There are some small imperfections, but this is the point where I usually ruin good enough trying to get to perfect so I'm going to stop. I sprayed one more thinner coat over the whole tank like you...

    78 GS 750 Rebuild

    So I sanded in long broad strokes over large areas. I stopped sanding when all the guide coat was gone in an area. I did break through to bare metal in some areas (even with the 400 grit), there's still plenty of primer in other areas. The area in question (against all advice) I sanded a couple...

    78 GS 750 Rebuild

    The humidity has been hovering above 90% for quite a while now, sometimes as high as 98%. Looks like I'll have a window between noon and 7 pm tomorrow where it's supposed to drop down to 60-65% humidity. Should be more than enough time to get to clear if all goes well. There are 2 spots right...

    78 GS 750 Rebuild

    Thanks Lars! I'd say your build is incredibly thorough and detailed as well. :eagerness: I've been following along, and can't wait to see yours on the road. For me... Right now I'm sitting in primer, and I think I have the tank as good as I'm going to get it with primer and block sanding. Now...

    center stand...trick to get it up on it...

    I've done it in flip flops before. Seems like you've figured it out, but definitely get yourself the grab handle. Makes it a lot easier...

    78 GS 750 Rebuild

    Not invasive at all. You're advice and suggestions have been invaluable! Especially this bit right here... How did you know that's what I was worrying about? :confused: :-k As soon as I stopped being concerned with hitting bare metal and went to town, things started looking really nice...

    78 GS550 engine rebuild

    I know this one guy who went to the emergency room with severe chest pains. They rushed him into the O.R. and performed open heart surgery, a quadruple bypass... Turns out he just had really bad gas from a burrito he had for lunch. Ok, so I made that up, but I agree with Nessism and ChicagoBob...

    78 GS 750 Rebuild

    OK, I guess I could have gone a lot farther on the last round of sanding then. As soon as I hit bare metal in a tiny spot on the sides, I stopped. As soon as I saw the etch primer peaking through on the top I stopped. Whatever guide coat was left got primed over again... I re-shot etch primer...

    78 GS 750 Rebuild

    This is after block sanding the primer. The guy at the paint store put a blue tint in the etch primer. I wouldn't have thought to ask him to, but it was super helpful to see when I needed to stop sanding. When gray turned to bluish gray, I knew I was about to go too far. Larry, what you told...

    78 GS 750 Rebuild

    After that last bit of advice I decided against trying to skim coat the whole tank again to keep trying to "get it right". I just filled in the air holes and touched up some problem areas. I didn't get it perfect, but I got it the best I could with my current level of ability and experience...

    Oil filter cover stud removal

    At this point, you're going to have to buy, rent, or borrow a drill. I've been in this predicament. Not with filter studs, but other broken bolts and studs. Don't bother with an ez out, you'll just potentially make the problem worse if it breaks off (which happens a lot). Start with a small...

    I'm starting to learn the language a bit. Not well enough to carry on a conversation with some locals about the dangers of inflation and the looming possibility of having to devalue the currency...but enough to order a beer, ask where the bathroom is, or get directions to the museum...

    78 GS 750 Rebuild

    I was definitely sawing away for what seemed like a lifetime. I did hit it initially with the RO sander to knock down the big lumps and lines, but then I started to hit metal in some spots while spots next to it were still super thick so I stopped. The spots on the left were definitely solid...
