i didnt like the scratchy abrasive type liners so for my CJ5 i wend with a kit made by Bondo, it was much smother and flexable, held up to the sun great and was really easy and thick to put on. my only complaint was that it was a two part epoxy type with a hardner and you had to mix the whole gallon at once, with a limited pot life for 2 coats. it was about 50$ i think
