Some drivers experience loose screws, and others do not. The ones that do not, and have tried loctite, have had to drill screws out of the bulkheads at times.
I would suggest you put it together without the loctite first and put it through an entire race day. Then check the screws and use the loctite if you need it.
The various opinions may just be a matter of differing hand/arm strengths (torque).
