Re: Tender Tank
I used Devcon Flexane. Other options are paint on truck bed liner from PQR
Too many things going on to bother listing them.

Re: Tender Tank
You're going to get a thousand responses to this. I used a gas tank sealer called Gold Standard from KBS coatings. It's made for sealing and protecting the interiors of tanks. There is also an aircraft grade sealer for aviation fuel tanks. I don't know much about it but I'd think it would be good stuff.Steamingdanny wrote:What do guys use to seal a tender?
Regardless of what you use, success is dependent on properly preparing the metal before applying the coating.

Re: Tender Tank
Had good luck with this process:
1. Wash tender thorougly with Acetone.
2. Take tender to powder coating shop. Ask that it be "pre-baked" to burn off any residual oil. Then sandblast, powder coat, bake. Let the powder coating shop know that you are trying to seal the corners/rivets. They might be able to help when shooting the powder coating. Cost me $30 to have 3/4" scale tender powder coated.
3. Seal edges/rivets with POR bed sealer. Bought a small can thru Summit Racing. Brushes on easily. Doesn't run out the openings. Cures quickly. Cleans up with water. Label says no shelf life and nicks can be touched up.

I couldn't resist....
How about sealing a tender with Phil Swift's Flex Seal? It even works on a boat sawn in half! lol
Yee Doggie!!!!!

TimV,
I like the powder coat and bed sealer idea.

I got some 316 stainless, 0.070 thick for a great price at a junkyard.
I had it waterjet cut, both the outline and rivet pilot holes.
To my surprise, the rivets (properly set) are water tight.
The only sealing with solder I had to do was the bottom row - the rivet tool could not be perpendicular with the rivet and it didn't fully set.

BTW - there are 2300 mostly stainless steel rivets, the rivets above the water line are brass.

Nice work on the tender! A good idea on how to machine the beading. I am at the same point with my Climax cab and tender beading.

Re: Tender Tank
I went to local sheet metal shop had a galvanized box made. Soft soldered all of the joints. The last one lasted over 20 years and it only cost fifty bucks. Mounted it on 1/4 inch wooden spacers for ventilation and allow any spills to dry
Re: Tender Tank
I used 20 gauge CRS for the tender of my little 0-6-0 switcher. It has a custom-made plastic insert tank with a baffle. The tank holds about 13 gallons or so. This relieves me of all the corrosion-related maintenance issues and no peeling tank sealer to deal with. Another benefit is the open side legs in the tender that I will use for the battery to power lights, etc. It's an extra expense for sure, but it will more than pay for itself in reduced maintenance costs and aggravation from having to disassemble the tender periodically.
