OP, I wouldnt get scared off from some of the posts here. I had a similar type of question and was scared off by concourse grade individuals that basically made me out to be an asshole for even thinking of doing repairs on the cheap. I lost a couple of years with an old van as I was afraid to put bad money into it. I copped on fairly quick and got it to a state where I could enjoy and got a food few years out of it before needed to be done again.
If the repair is solid, but the paint is shoddy and lets you get out on the road. Do that. If it needs to be done 5-6 years down the line again, what of it.
The main point is to get out on the road and enjoy your classic.
