Rules for Posting Guides on Our Community
1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.
2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.
3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.
4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.
5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.
6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

MODERATORS
Years ago I was watching a documentary about trash and recycling. They interviewed the garbage truck driver who said people have to be careful what they throw out. The containers can be ruptured in the back of the truck and can mix. He mentioned brake fluid and powdered pool chlorine and coca-cola and powdered pool chlorine can be dangerous. One combination makes a poison gas, the other spontaneously combusts.
I think linseed oil on rags is one of the big ones that will spontaneously combust.
When I was painting cars, too much catalyst in composites can be one that gets hot enough to burn skin easily. I never had it combust but it felt close to hot enough a few times. One of my cheap and fast hacks is to use fleece fabric with fiberglass composite type resin. It soaks up a ton of resin and will take a shape in one go as something of a base molding form that can be worked with course shaping tools. That thick of material full of one mix of resin gets super smoking hot when the catalyst goes off.
