Theres always a next time i didnt do much apart from watch and take some pictures, it was one of my friends who was more hands on if im honest.totally agree about powdercoat vs paint. Nothing beats a good prep, primer and topcoat. Once powdercoat chips which it does easily, you're pretty much screwed
Whoever told you burning the bushes out was a melon, get a hammer and knock them out ( hit them on the inside of the arm so they come outwards ) it takes about 1 minute to do if you got a good hammer. Ive just done mine and was shocked how easy it is, they were original bushes too.
You still have the outer metal casing of the bush stuck in the trailing arm so you'l still need to hit it out before putting new bushes in
