Propane tank corrosion
I am a little concerned of the corrosion spots in my tank
If anyone could take a look in the pictures I sincerely appreciate it.
Any general recommendations will be great, I want to send it and repaint it and put a protection
Like peel and seal aluminum asphalt, to prevent rocks in the highway.
What you think?

I don't know how old that tank is , but that's a lot of rust.
JMHO: Get the manufactures name off the tank and price out a replacement , the pitting is too deep for a sand down and repaint .
Cover the bottom of the new tank, with roll on pick up bed liner ; white preferred , some places have issues filling painted tanks.

MH ASME Propane Tanks are thick walled
Sand it, wire brush it, repaint it
No need to replace it

I would use POR15.
I havevseen many recommendations and used it for a batty tray refurb and now convinced it is very durable.
I believe it comes in white but can be painted over, in fact recommended where exposed to UV.

My first MH the tank looked like yours. I went to the propane folks and ask them what to do. I was told to wire brush and light sand. Once the area is clean spray with automotive undercoat spray. I brushed and sanded the whole bottom and half way up the side of the tank. Sprayed it with the undercoating and it lasted for many years.

Agree with Old Bisquit - just sand or wire brush and paint it with a quality finish. Use a rust inhibitor if you like. POR 15 or similar can be used as well.

My tank looked similar to your picture. I decided to remove it from the rv and repaint the entire tank surface. Cleaned the rust with a wire wheel on a grinder and like mentioned used POR-15 on the rust areas. I used white appliance epoxy paint for the topcoat and two years later it remains rust free.

Do MH tanks require recertification periodically, like the portable bottles do? I am just curious, as I don’t have a MH.

No, completely different requirements as the RV tank is considered a permanent installation rather than portable.

What Sweebriar said up there. ^
RV tanks are ASME, and vertical (like grill and RV) and horizontal (like forklift) cylinders that are portable are DOT jurisdiction. ASME has no recertification requirement.

I would agree with Winemaker2. I have repainted the LP tanks on both our 2001 Adventurer and our 2013 Adventurer with POR15. They turned out great and I doubt I'll have to do it again.
In our case I removed the tanks so I could get to the entire surface area. I sanded them down with an orbital sander then followed the instructions for the POR 15 paint.
I used the 3 step rust system with a top coat of machinery grey Krylon spray paint. I did the 2001 in 2006, and it was still spotless when we traded it off in 2013. I did the 2013 in 2016 and it still looks bright and shiny today.
If you follow the POR 15 instructions to the letter you'll get a good finish that in all probability will last a lifetime.

What you think?

I have to do mine as well but I think I'll wait until it's close to empty since it's more then likely heavy.
