Also, just be cautious with things like self amalgamating tape. It certainly has its place, but one of the stated aims of a lot of IVA inspectors is to see kit builders using solutions and methods you’d see on a mainstream manufacturers vehicle. Yet at the same time, many have something of a dislike for certain uses of adhesive tape and stuck on covers.
They used to have a favourite trick, where you’d used what they considered to be an unacceptable method of covering/fixing something. They simply ask to examine what was underneath. So you’d cut off the covering, and then they’d fail you on a lack of covering, unless you had some proper way of reinstating it, there and then.
Whereas tie wraps, which you can quickly replace with fresh, and split tubing, they seem to absolutely love!
