If you want your paint to lay clean, last long, and not haunt you later… this is the lesson.
We just dropped the full Surface Prep Process Guide (Grumpy Commentary Edition) inside the classroom. This one isn’t fluff — it’s the real step-by-step breakdown with the shop wisdom most guys only learn after redoing a tank twice.
We cover:• Proper metal correction before filler• Blocking strategy that keeps tins straight• Primer discipline• Final sanding reality checks• The mistakes that cause 90% of bad paint jobs
Remember — paint doesn’t fix prep. Prep determines paint.
Go through the lesson, download the guide, and drop questions below if you’re working on a set of tins right now. Let’s see what you’re building 👇🔥
