Craig’s three rules
Plan ahead. Get the bits you’ll need with your end result always firmly in mind. Change your mind on certain things, but don’t change the plan.
Take your time. Rushed work always shows. Sit back, think about it and you’ll usually only have to do a job once.
Measure twice, cut once, and always get a painter to do the paint. It’s a skill, so use a pro. Same with ally welding.
