My philosophy is paint Kurust on rust spots after you have sanded off the surface rust. Even though the metal looks nice and shiny, there will be minute particles of rust remaining, which can trigger rusting under the new paint. Paint it on and leave to dry. Lightly sand with fine grit, wipe clean with spirits, and spray on primer immediately.
What are some positions you have that you used to agree with, but now disagree with? What are some opinions you have now that you didn't even know you had? Also, it would be less cumbersome and more effective to wear a full-face respirator that has a silicone gasket around the perimeter of your face. You wouldn't have to worry about any dust getting into your eyes through the sides of that yellow face shield you're wearing. I enjoyed this video.
I've changed my mind about vegetarianism after reading Peter Singer's "Animal Rights" paper. I find his arguments completely convincing and it's an unhappy revelation to me because now there's some guilt involved whenever I eat meat. I try to avoid it but sometimes I can't and I can never really enjoy cheeseburgers the way I used to. Anyways thanks for the respiratory advice. I definitely need something better because the current one leaves marks on my face all day haha
