Forty years ago I completely dismantled everything including brake cross shaft and took the bare chassis to a blaster. Shot blasting can be too aggressive for thin metal and the whole thing could be distorted. Grit blasting is best for a 7 chassis. My bare chassis could have been put through a blasting mill on a conveyor for free, where father in law worked, but I was advised against that. So I got this professional blaster to grit blast it. can't remember the cost, but with a new mortgage and 2 young kids and a stopathome mum, the price can't have been too bad. We collected chassis and it looked very clean and vulnerable. Rushed home with it and brushed it with an anti-rust primer. Sprayed next with a couple of coats of cellulose primer filler. Then sprayed with celly black gloss. Chassis was then put on one side for well over thirty years in a large garage with dehumidifier. About six years ago it still looked perfect and glossy. It was then built up into a car and I've still got it. Been driving it for four years or more.
