I have recently installed new rocker panels on my Cherokee and wanted to use a bed liner for them but noticed most were very expensive so I bought a couple cans of spray undercoat. After only 3 weeks when I powerwashed my Jeep the undercoating started to come off. Does anyone have an alternative that would hold up but not be too expensive?

 

the spray can bedliner is crap, period. and undercoating is not meant for the body panels

if your trying to go cheap then the roll on bedliner will be your best bet.

you can buy qts for around 20-30 depending on the brand. and 1 qt will be plenty to cover your rockers, and you'll still have a lot left over

 

i would go with herculiner, i did my interior. Its cost about $110, dont know ur price range but definitely worth the money. Come with rollers, 1 gallon bedliner, and so far has stood up to what ive thrown at her. You would have enough for ur rockers and anything else you want to help protect,

 

I used duplicolor bed liner spray from pretty much my door handles down. I would recommend it, it's been on my jeep for over a year with no peeling or cracking. Preperation is also very important, if you have clear coat still then it needs to be scuffed up or sanded off.

 

Thanks for the input. I almost bought the herculiner before but it was a little pricey like you said $110 but is probably worth it. Im going to look into the duplicolor bed liner as well.
