Troy may know SFA's but he doesn't know bedliners.....
Why would you tell someone with no experience to go get a paint gun and a $1500 air compressor...
Especially when it is a Permanent Application.
You have painted before... I'll be an ugly color

But you have experience and equipment...
This pretty much sums it up.... (FOUND BY SEARCHING BEDLINER)
First of all,
the man behind the gun is a huge factor in sprayed bed liners. Don't get hung up on a name brand. There are low- and high-quality applications in any brand you choose.
Rhino Linings - One of the first (but not the first) companies to do sprayed bed liners in North America. They use a cold, low pressure system to apply 100% polyurethane. Their chemical isn't the greatest. In fact, it's far from it. For general use in truck beds, it's adequate. For heavy use/abuse it's too soft. The chemical seems to fade & chalk much quicker than some others. It's a relatively slow setting formula that makes uniform thickness difficult if not impossible.
Line-X - This is a hot, high pressure application system. The advantage over the "Rhino" system is faster setting formula and better control of material thickness. Their formula is more brittle (poor elongation) than some others. Super-fast gel time nets a dull appearance and sandpapery texture. Still, of all of the "national brands", this is one of the best systems.
This is why they added line-x with Kevlar
Speedliner - If there ever was a misnomer this is it. This is one of the most primitive application systems. They use a low pressure batch mix (solvent based) that's extremely flammable and very slow to set. Plan on your truck being out of commission for days. Due to the extremely slow cure,the operator cannot control thickness worth a darn. The finish looks primitive and the application is usually very thin due to the relatively high cost of chemical.
Herculiner (and most other do-it-yourself kits) - This is a do-it-yourself Speedliner, basically. You're paying $100/gallon for this stuff! What you'll end up with is a super-thin "bed liner" that looks like you did it yourself. Don't waste your time or money!
Bed liner "spray bomb" - If it's in a rattle can, it's paint! Do you realize how many cans it will take just to cover the bed? Do the math. Don't bother.
WORKMANSHIP - Many compainies take short cuts in preparation. BAD IDEA! We hand-sand and abrade all surfaces, then do a chemical wipe before spraying. Attention to detail is EVERYTHING!
Bottom line: A hot, high-pressure system is the best application method. Polyurethane/polyurea hybrid chemicals are the best formulas. Choose an applicator based on what you've seen of their actual applications. Don't put much credit in their "display" model. Look at the edges closely. Look for drip and sags. Look for anything that's not perfect!
Go get it done by a professional... Like Troy!
