I have recently bought a truck that was used to chip branches into unfortunatly it was a council truck so they left chips in the back to compost. I will use it for the same purpose except I will empty it daily.
We got in the back with a shovel, air chisel, and hammers and broke up the rust layered at the front and deep pits at the back (this is caused by something else perhaps fertilizer). We removed about 30 litres of rust but there still seems to be enough floor left to use, no holes.
Well my problem now is what to do there is still rust I have been reading all morning here and elsewhere about rust removal. Electolisis is a bit hard but other methods I have found are:
Deox gel to clean the rust off.
Phosporic acid to convert the rust.
Penetrol with Aluminium.
Fish oil.
In my old truck which had rusted through in places I chipped rust off painted with phosporic acid scrubbed and recoated a few times welded plates over holes and painted but the paint just wears off. This was a short term fix but it lasted till I sold it maybe 4 years. But this rust is more wide spread and not localised.
I was thinking of chemically cleaning off the rust maybe Deox gel then perhaps a paint with fish oil every year if I can find where to get either of them in Melbourne.
I have never used either of these products and maybe the phosporic acid is best?
I'm open to any ideas
