As stated in my introduction, I am quite new to woodworking. I am building a bunk bed for my younger brother and his two children. (Pointless background information follows): One of his children is deathly afraid of heights, even 2 feet off the ground he cried and screams uncontrollably. His daughter isn't even two so we have decided to do something interesting with these beds! Below is a picture of where I got my idea. He is going to sleep on the top! And his children will be in two toddler beds below. His bed will be a twin size. I have very limited space for them so this is my only option.
I understand I have already done some stuff wrong, but currently tight on money for this project.
I purchased 2 4x4 beams of dougfir and sanded them to 320 with a random orbit sander with a ceramic 320 grit pad.
I went 80-220- then 320. Not sure why... just seemed right at the time.
The beams turned out very smooth, maybe too smooth.
Due stupidity, I grabbed the milwax brand of stain. I put one VERY light coat on. I let it sit for 20 Hours at the time of writing this with a fan on it over night.
I would like to seal it now to give it that protective coat, however all I have in my shop is some rustolium lacquer spray. I would like to use something better, maybe thicker. I have my doubts about this lacquer spray, I tested it out on a piece of pine i stained and i could flake the lacquer off with my finger nail.
Here are my beams, I router two of the edges for specific purposes. What sealer should I use? I don't want to ruin these beams.
