If I wire brush rust on my tank but do not arrive at bare metal but more rust, I must either arrive at bare metal or prepare to " invade the tank" as^not arriving at bare metal means I am about to puncture through. I have not gotten that far but think this might happen. LP is turned off and if this happens obviously I will discard tank. Doug

Don't "discard" it. In fact, why bother with the rehab. Trade it in at your nearest propane exchange center. Unless, of course, it's not a 20 lb tank. I don't know of anyone who exchanges 30 lb tanks.

ASME tanks are made from pretty thick hard high carbon steel.

If the tank is rusted enough to be condemned I’m pretty sure the RV frame that it’s bolted to is LONG past being safe to go down the road.

You don’t need to get down to “bare” steel, you just need to get all the loose rust off and slather it in white rust paint.

Jax, I will take your advice and get surface rust off and put proper follow up rust protections on. Onan tech who removed my old no good genset told me the frame rust was only surface rust. Doug

+1 to remove the bulk and smooth the surface a bit and paint with a rust inhibiting paint.

I have had good luck on truck and trailer frames with POR paint.

That... Is a post I agree with.. If the tank is that far gone odds are the RV is too... My last car was fast approaching that point when the settlement check arrived for my RV (It got totaled. which as I discovered later was very likely a very good thing for multiple reasons) my "new" used JEEP has many years left.. Save for one foot that leaks.. about 2PSI per week.


Home was where I park it. but alas the.

Not a portable tank. Thanks for the replies. Doug
