When I bought my 73 three years ago one of the selling points was that there were no cracks in the dashboard. I've taken good care of it - it's cool here in Flagstaff - and I regularly use windshield sun-screens, but despite this I noticed this week that I've gotten a crack in the dashboard.
Is there anything I can squeeze into it to make it cosmetically better and maybe even keep it from getting larger or longer? I thought of using some black RTV, but I don't know of anything else that would be a candidate and I don't know whether it would really work at all.
Any ideas?
