I am ready to get my roof and rocker panels done, I have been googling DIY kits, everyone has an opinion but, I am leaning towards the Durabak kit. It's peel free, UV resistant and is sound dampening. Priced fairly at $130 ( gal kit ) and it comes in 12 colors. Since my Disco is Plymouth blue I'm going to the roof and quarter panels in blue, black or sand color. Does anyone have any recommendations on a good DIY kit? UV is a big factor as I'm in Bakersfield and Las Vegas regularly. If it matters, I have a 1994 Disco 1, just hit 142k with no rust.

 

There's a load of info on ih8mud about liner application. Using their search tool you should turn up a lot of info.

I haven't seen any prices on their site yet but this sounds like a good option so far. I'm shopping for some black right now to put on my FZJ80 bumpers, rockers and fenders.
*Edit, found pricing. Looks pretty reasonable.

 

That Lexus looks good, I am awaiting a sample from Durabak, emailed yesterday and they replied within an hour advising my request was received and product would be sent out in the following days.
