  1. Back in the summer there was a thread about a German product, a paste made of Citric acid and sawdust. I can't find it at the moment but I have been playing around with Citric acid for a couple months now and it has become my go to rust remover. I have found all the other acid rust removers have some drawbacks to them but Citric has the fewest so far. It is very inexpensive especially the industrial grade, I didn't want to purchase 50lbs until I knew it was worth it so bought 10lbs of food grade. 2 cups of dried powder in about a gallon of water makes a strong solution. Your results may vary depending on the hardness of your water but it should be easy to repeat these results. The test piece is from the KA24DE engine I'm using in the 510, 2 cups of Citric acid in a gallon of water, all I did was scrape the worst of the flaky rust off. The shop is cold, just above freezing, when the water is room temp in the summer rust removal happens a lot faster. If you splash some on your skin you just rinse it off, there is no drama, no burns. These next 2 pics are after 20hrs soaking, took it out of the bucket and scrubbed it with an old wire brush and rinsed. The last 2 pics are after an additional 24hrs. Now that might seem like a long time but I have lots of that so I'm good. Muriatic acid is 10x faster for sure but I have never found a way to completely neutralize it, the rust always comes back under the paint, so far that has hasn't happened with the Citric acid pieces.
  2. Thanks Mike, I just ordered a strip to try it out.
  3. Too bad about the sunroof but at least it looks like it's one of the better quality jobs.
  4. OMFG, where do you find things? I just don't know what to say
  5. There are some serious hours of prep on all the plated parts, it paid off, every piece looks perfect.
  6. Unless of course you're filthy rich, then you can just breeze right through, https://www.cbc.ca/news/canada/liz-uihlein-covid-19-diagnosis-1.5801118 The area where I live in the province of Ontario is right on the verge of a lockdown at the moment, we hit 1600 new cases in one day last week. They say once we hit 2000 per day then the Bell curve takes over and then it will just skyrocket. I'm just going to have to kick the breathing habit.
  7. That's one of the reasons why we're heading back to the moon, despite the agreements that were signed 60 yrs ago about no country claiming mineral rights or territory on the moon, you can bet your life that if a cost effective way is found there will be mining.
  8. Oil slinger? Didn't they delete it on later L26 and L28?
  9. An oldie but a goodie,
  10. And that's a fair price for what you get considering you would have to dump $30k more into it.
  11. Hard to beat the Euro spoiler when it comes to cool.
  12. Rich women have to have something to spend their money on.
  13. Who makes that panel and why on earth would they put such a badly fitting piece on the market? It's not like it can be fixed or modified to make it fit either.
