Gap tool question

[Rg500gamma]

I was intending to use paint stirrers for my gaps for the doors front fenders and the hood. Is that a reasonable distance or do other members use different tools ? I also need the gaps to obviously be close enough for the weatherstripping to be close enough to do their job.
Feedback is GREATLY APPRECIATED.

A paint stick is probably going to be too thin. It might be more like two paint sticks, or something. Just center everything up to what looks good. Then you can measure that gap and find/make a shim, to fine tune it with. If needed.
