Make sure you use solder safe for electronics. Don't use acid based solder (used for plumbing). Get some solder with a rosin core which will help the solder flow well. I still prefer to use lead based solder, easier to work with it's lower melting point.

Kapton tape is some pretty amazing stuff. I use it in the lab fairly often. Great electrical isolation properties, and the temperatures it can handle are beyond extreme. It could care less if you place a hot soldering iron up against it.

And the new Radio Shack catalog every year. Like the the Sear's Toy catalog.

It's rosin core and mentions electrical - so that part sounds OK. It's silver bearing solder, and if I'm not mistaken, has a much higher melting point than 60/40 (tin/lead) solder. So given that comment, I'd likely be concerned w/small parts and PWB damage from heat.

I've used silver solder on parts years ago that required silver solder...sure did need a higher temp to flow well. A PIA to use. Not sure of the 'bearing' part of silver bearing.

Looking at the HD web site, they have leaded solder, but the diameter is rather large (0.062") - that's a bit much for parts, but for wires -no problem.

Here's some Amazon stuff if you want smaller: https://www.amazon.com/HGMZZQ-Solder-Electrical-Soldering-1-0mm-0-22lbs/dp/B07BGY99SN/ref=sr_1_1_sspa

Just my 2 cents!
