When I started at my uncle's shop 10 years ago. He had a very basic website that was done by his friend. A few years ago I decided that it really needed an update. It was graphically a mess, to be honest it looked like a geocities site from 15 years ago. I'm pretty good with computers so it was natural for me to do it. I believe that a small business like this has to have a smaller web footprint, meaning that it should feel like a couple page ad in a magazine, not full a catalog. And should not have to have constant updates. Every year or so for an update, I also see if it needs an overhaul to change with the times to not seem dated.
What I did was make a few notes on what information we wanted to put on there. Basically our location, hours, services we offer, a gallery of completed projects, and how we differ from the competition.

We don't have a business Facebook page. While I do have a personal page and have referred people on car groups that have asked where to get work done, I refer them to the site. To do a Facebook page would require more work. I'd have to post once a day/week. To be honest the content I would post wouldn't be very interesting. The regular day to day posts would be boring. People like to see fun projects getting completed, not basic repairs done to work trucks. I can see if you have a shop that just does those fun and interesting restorations having to have a Facebook page.

We use binks. Don't know the models, they are 2 gallons.

I had to order from here for a vintage Mercedes. They wee easy to deal with.

I have had good luck with purple power. I keep a diluted down spray bottle on hand.
