If anyone is considering using a bedliner (herculiner, durabak etc) on their hardtop then my advice is to go for it. I just finished fiberglassing all my cracks and missing peices in my stock 79 hardtop, sanded it down good and Herculined it. To my surprise it actually looks really good and I think it's going to last for quite awhile longer. (Sorry I don't have any pictures). If I have any advice for doing a hardtop it is: Sand it down nice and even. Make sure it's absolutely clean (use xylene like the instructions say). Mix the living crap out of the herculiner (used an electric drill). Do it outside (the xylene fumes negate the need for beer). Start with the roller and do as much as possible, then go back and do the trim with the brush. (this helps to keep things even). Take your time and make it as even as possible. However it looks when you roll it on is how it's going to dry.
Overall I am very pleased with the Herculiner. One question I have is if any one has had any experience with Herculiner and fading in the sun? If so what can I do to combat this? If anyone wants to no more about this let me know.
This has been covered several times. If you do a search you will find more than you need to know about Herculiner. As far as fading goes, supposedly you just need to coat it with a clear coat that has UV protectant.
Yep, it does fade. I lined my old cj tub, before deciding to go to fiberglass, so I just left the old tub lying in the yard. I did not take any precautions or have not been washing it, and it did turn a dark gray color (might even call it light black). Other than the slight fading, the texture has held up real well, and I would recommend the product.
