72 duster resto
Also regarding engine and engine bay cleaning, I recently did same. For the engine, I used the Gunk Brand GEL Engine degreaser.... Did it once and it took off a lot, then spent some time with a scraper and wire brush to scrape off some heavier areas, and then did the gel again... worked well and I'm happy with the paintjob on the motor.
For the engine bay, mine was pretty ugly with a lot of old ziebart undercoating everywhere... I ended up going the mobile blaster guy route... I was able to find a local service who came out for about 1.5 hours and blasted the engine bay, bottom of hood, and a handful of brackets for about $400 - Honestly, this was some of the best money I've spent on the project since I started it. Few before/after pics in my build thread if interested, but I'd definitely recommend this route.
