How to remove bedliner
Ok so when i bought this truck it had some crappy bedliner in it(spray in). It needs to be removed and the surface rust on the bottom also needs to be removed with it.
Multiple people have told me that to have someone sand blast it, would cause the metal to warp? So i see this as the only way to remove this crud.
So, how do i get rid of the rust, and the bedliner? (there are no rust through spots anywhere on the truck)

I dont really know for shure but I would think putty knife + wire wheel on hand grinder + many hours labor= bedliner free bed. They might be able to blast it out like you said but they would probably just use something like wallnuts? instead of sand so it wouldn`t end up pitting the metal.

Hmmmm. So sandblasting is prety much out of the question i guess.... And this stupid bedliner is flamable. I lit a piece on fire earlier when i was seeing if you could cut it out with a scraper and torch.... It really burns!!!!
And what are my options for removing paint from the exterior?

I've sometimes wondered how you would remove that stuff. I still think you could sandblast it, if your carefull. Hold the tip at the right angle and peel the stuff off with it, when you get to metal, keep moving so as not to warp it. Even if it did a bit, we're talking about a bed interior that will most likely get another liner, no? I dunno, I see no other practical way to remove it. As far as paint, there are chemical strippers but why do you want to remove it? I'm no P+B man but there is no real need to get to bare metal. You might ask in the P+B section.

As far as removing the paint, there is rust bubbles and it is cracking and sun burnt everywhere! So its going to get a complete restoration as soon as i can come up with the money. There has been two coats of paint on this thing and i want to start fresh so i know what under the paint thats there now.
I need someone to sodablast it or use walnut shells but i cant find anyone

how about trying a heat gun and a putty knife to remove the bed liner. I don't think a heat gun would get it hot enough to burn but it should get it hot enough to be soft and pliable, then you can scrape it off.
It will be a lot of work but what isn't?

Sand blasting large pieces of sheet metal with sand is a bad idea. No matter what angle you hold the nozzle at. To save yourself time, if you want to sand blast it, cut the quarters off of the bed and run over what's left with your truck. Yeah, it'll be about as usable then as it would be if you sand blasted it. You just wouldn't believe the damage it causes.
I like the heat gun and scraper idea. Just get a good thick scraper. A drywall putty knife won't do it either. I have an 1 1/2" stiff scraper I put a sharpened edge on that works great for stuff like this.
As far as the outside goes, 80 grit paper on a D/A sander. I like to do investigative work as I strip the vehicle. I take it down (quickly) layer by layer to see what was actually done. Sometimes what appears to be two coats of paint is actually three or four with a collision repair in the somewhere.

You could try Aircraft Paint Stripper. Just brush it on and leave it for a bit and scrape it. It eats paint pretty good, Im sure it would handle those cheap bedliners too.
Id use the torch or the heat gun on any tough spots.

Unfortunately, when you to try sandblast undercoating, (and I can only assume bedliner because it is similar,) it takes a ton of sand, time and patience. Because the product is sort of "elastic," it absorbs the energy of the sand and does not come off. I have run into this numerous times. As for blasting the bed of the box, there is enough structural integrity that I would not be afraid to do that, once the bedliner was removed.

Don't let your wife use it as a hair dryer either. Probably burn the hair off her head

Well here is a good one 4 ya. Its some kind of airplane paint. 3 guys at maaco and a spray in bed liner place said the same thing.... And they said i have to rhino line over it. Crap!!!!
A friend of mine is going to take care of the minor rust bubbles by spot sand blasting. He has somekind of mini sand blaster and we are going to use it just on the rusty spots so i dont destroy the truck.
