Here are some best practices learned through lots of research and trial and error.

Paint removal was done on trailer with trailer jacked up on jack stands for more height. Once 90% complete I rolled boat off trailer just enough to get where axles and beams were.

The method of removal started with Citristrip covered in saran wrap and let sit for 24hours (more than 24 hours had limited effect and began to dry). Scrape a layer or two and re apply Citristrip and cover again and wait 24 hours. At the second scrape I was able to get to gel coat and perform some rough scraping. tough areas Citristrip would loosen up within an hour. All scraping was done with a 3 inch razor wall paper scraper, once dull it worked better, paying attention to not gouge. Work 3-4 foot sections. This took 3 weeks.

Wet sand by hand with 220 grit to remove all gel coat discoloration and small missed spots. Next quick wet sand with 500, 1000, 1500, 2000.

Using polisher 3m compound, 3m finesse it polish, hand wax around water line and v.

Decided not to have boat soda blasted as I did not want to lose gel coat or have it pitted too much.
