I just had a massive fail on the Rustoleum bed liner. While I had the belly pan off in order to get better header pipe temperature reading, I decided to clean the inside of the accumulated road scum and debris. I used engine degreaser and when I hosed it off the liner came with it, it peeled off in sheets. Had to spray a bit more degreaser on a few parts but it came off real easy. I really liked the look of the Rustoleum and it was standing up well. I've had a look at the can to see if there was anything about chemical resistance but there is nothing except clean up with Xylol or mineral spirits.
So now I have to decide whether to buy another can respray and avoid using chemical cleaners or find something else. I went to Supercheap and had a look at Septone stone shield but the instruction state that it must be top coated with paint which doesn't make a lot of sense. I also looked at Septone body deadener and Duplicolor rubberized coating. There is a couple of paint specialists a few K's away so I might give them a try for a bit of advice.

But you failed to answer the more interesting question of what and where the bed liner was doing there in the first place!
-
I used it to stop stone chips on the belly pan. I've got a black K75s and due to riding on dirt roads the belly pan, even with a longer than standard mudflap gets a blasting. The bed liner was applied to the front and bottom of the pan and didn't look out of place. Now I have to decide which way to go.

Sounds like the original surface that the Bed Liner was applied to was not free of dirt, oil or chemicals, and this prevented the liner from bonding to the substrate. Preparing the surface for paint is everything!
-
It was cleaned with wax a grease remover over brand new paint.

Did you skuff the surface to give the paint a key and apply a self-etching primer before the bed liner application?

Very important!!!

I didn't have the heart to scuff up the brand new paint just in case I didn't like the outcome. However since it was applied in March 2016 it has lasted well with no sign of damage. That was until I decided to clean it with degreaser it was going well, and did look good. I have thought about it and maybe the fact that it can be removed with degreaser is not necessarily a bad thing. I will wait until I visit a couple of local paint suppliers on Friday. I am also pondering just recoating it and avoiding the use of degreaser and it's like. http://www.motobrick.com/index.php/topic,7643.msg58286.html#msg58286

How about a different solution? You can buy strips of thick clear tape that are intended for the inside of car doors. Just heat it a bit if you need to mold to complex curves. I used that tape on a carbon-fiber belly pan on one of my Moto Guzzis. You can't even tell the tape is on there unless you get down close to inspect it.
Here's a roll of the tape on e-bay:

If you use the tape, you'll be glad you didn't use abrasives on the paint before. :2thumbup:

Scud I've previously used boat anti skid deck tape and used heat to mold it, but eventually water would get under the edge and it would lift. I am in the middle of repainting it with bed liner although I couldn't get Rustoleum locally. I ended up finding Duplicolor bed liner which I think is pretty much the same. Just cleaned off any old residual liner and then used wax and grease remover on it. I think it would have lasted if not for my using degreaser. I wrongly assumed bed liner would be reasonably chemical resistant due to what people throw in the back of their trucks. I wont be making that mistake again.
