just had mine done recently,coz from lots of his customers rides and his,d rust problem doest seem to appear even after 3-5 years..his wira he did it 5 years ago,till now still looks new..another iswara,3 years n still looking fine..fingers cross,mine will last..
The problem he said is d gam that is use 2 stick between the bone/crossmember of d roof..so if u get d top resprayed but did not treat d bottom half of d roof,it will definitely appear again..a good body repair shop sud knw how 2 do this..scrap off d old gam/glue and use a better non corrosive gam/glue..
yeap yeap from my understanding proton used a metal based gum before year 2000 when manufacturing their cars so that why it rusts not to sure on this though
so where did u do this job bro and how much did it cost??
did u replace the whole roof or something else??
