I'd like to say you're right, but paint prices, especially in the last 12-18mo will be WAY more than all the trim, pinstripes, moldings and weather-stripping, unfortunately.
Prices on all the trim and gaskets/weatherstripping hasn't gone up much of at all, really. It's low demand, vehicle specific stuff.
I've got about $500 all in, into every piece of trim molding and pinstriping on the truck, except door seals and hood to cowl seal. Both of those were like new.
Paint, whole truck, 2 stage, quality. A little over $1k all in, enough for whole truck, every surface save for inside of cab (which I have enough for too). That was fall 2020 super sale price. Today, same mfg and paints, about $2k. Go to a paint store and get top of the line brand and top line of their paint, you'll be in for probably $3k.
Single stage, could cut that down a fair bit, but unfortunately decent paint will run you way more than the trim and weather-stripping.
