OK, so I started on the hardest dent first thinking that I can't make it look much worse.
Yes, it's hard to do. Every time you glue one onto the skin it has a different adhesion. Sometimes they rip the clearcoat off, and sometimes they hardly stick at all.
Here's a couple more pics with my iPhone in the same light and reflection right before I started.
Here's the first couple pulls. You can already see where the glue has pulled off a patch of clearcoat.
When I was working on this large creased area, I used a line of glue across the tabs to attempt to just pull on the creased area instead of the whole tab size.
Not sure if this is really any better. But this is only with about 15 min of work, and on this session I spent about 60 min. working the dents.
I took a scrap piece of corrugated plastic and some electrical tape to emulate the line boards that the pros use. Not that it helped too much, but it makes it easier to see the dents, or what needs to come out, and what needs to be pushed back in.
I watched more youtube videos on the process and cut the handle end of a toothbrush off to make my version of a "knockdown". When you pull a dent out, the area you pulled on, or the crowning around the original dent. This is definitely an art form. The rounded end made little dimples, so I used the flat end (that I cut and sanded) and it worked pretty well.
Here's some detail where you can see the clearcoat pulled off, and how the tabs made a high spot. BTW, I'm going to strip the clearcoat anyway, so I'm not too worried about it.
I'm going to keep working on it. This is something that I consider as training. I'm sure this is not the first dent I'm going to repair in my life.
When I tried to level my pool table they said it should take 14 hours if it's your first time. A pro can do it in 90 min. After about 5 hours I hired a pro. I learned a ton just watching them. I called a couple of the PDR guys in my area and they wouldn't take the job. They said "Too hard, too much time, and you'll never be happy with the results" or "We don't work on Airstreams"
I'll keep tinkering with it as I have time. Or maybe on those long camping weekends when my thumbs are twiddling, I see if I can make it better.
Just to let you know, this is not a quickie fix. I wouldn't advise anyone to go into this expecting perfect and easy results. I'm posting these pictures hopefully to show you exactly what to expect. I consider myself a level 8-9 Handyman on the home handyman scale of 1-10. But I have more skills with mechanical than I do with bodywork.
