I have a question about how many coats of tru oil is recommended and are there any preferences. I have built a couple Spey rods and have been happy with the finish just not sure if I’m applying enough coats.
I usually go to about 10-12 coats myself. I'm not sure if it is more durable or not but I think if you look at the sheen and are happy after 6 or so coats you should be good. I also add a coat of carnauba wax after I am happy with the finished rod.
I use 7 coats wiped on with a piece of paper towel, then after the wraps cure two coats of Birchwood Casey’s gun stock wax as per Tom Bowden taught me. I prefer the satin look over varnish.
I wouldn't go for less than 10 - 12 coats . At that amount you'll get a durable matte or satin sheen. Given that you can put on 2 or 3 coats per day it's really no big deal in terms of time and effort.
If on the other hand you want a full gloss Its a bit more fiddly and time consuming but it can be done.
10 to 12 coats. I'll put as many as 14 to 20 coats on my saltwater rods. Not really sure if it makes any difference in durability. I do wonder if it affects the 'action' of the taper a little as more coats are added. As you gather the sections together after a few coats have dried, they definitely have that nice 'clack' of a hard surface. I've never thought to apply a layer of wax afterwards but definitely will from now on. Geez....always learning....
Tung oil has it's proponents in the rod making community. It is used as a base or sealer coat under top coats of varnish. It's just no match for varnish as a durable top coat. Tru Oil is a wiping varnish.
I have not had to do that just apply a thin coat with a soft cloth material and let it sit for about 3 hrs. I buff it with the finest steel wool and clean and apply another coat and when your happy with the coats let the rod sit for a few days before wrapping guides.
