rasta, its better meron ka spray on bedliner plus the plastic on top kc the cabliner wont get rusted that easily kahit hinid mo linisin or i.check, kung meron ka ikarga sa likod, the cabliner wont get dmaged or dented, just the plasctic liner lang ang madmage, which is more cheaper and better kesa mag weld or body work sa cabliner kung madented.. and thats the cause or start ng rust... iv used my pikc up loading up reallty heavy stuuf like oil barrel, which weighs about 100kgs or more... and it gets dropped sometimes on teh bedliner but wala naman sira sa cabliner, no dents or damage... so for me, much better kung meron spray on bedliner plus the plastci bedliner on top...
