Hi @Sinol i have done the following method on my pajero
1. Front side - fixed 8mm skid plate ( photo attached) from Al Jazeera turning sharjah. They will remove the stock Water tank guard and engine guard and fix the plate in that position.
Cost - 8mm plate with powder coating + fixing + front bumper lower cutting - AED 1090
2. Rear side - fixed a aluminium plate supporting the bumper to avoid scooping of sand.
Cost - AED 100 ( done in a garage in Ajman) details already posted in this thread, just scroll back.
So far both working perfectly.
