Thank you so much Asad Bhai for visit and for your valuable suggestion...
I fully agree that if floors are powder coated .....They are going to last a life time ....As you said that it will be burnt by welding at joints...so half powder coating and half Priming/painting will not be a good idea....Normally rust starts at joints first because due to welding/ heating ....metal becomes more prone to rust....Its less likely for the straight sheet to catch rust....After completion of undercarriage.....we will bring it back to bare shiny metal ....seal the seams thoroughly with sealant compound....Double prime it with DUPONT OF SEIKEN Primer ..then double coat of colour.......
Same treatment on both sides ....underneath and above ....so I think It should last for pretty good amount of time....At least in my life....:)....Hassan May keep it or throw it away ...... It will be up to him...
Please keep visiting and giving your valuable suggestions
Regards.
