Why would you want to add a plastic bed liner to your truck? Without some kind of liner in your truck, you must be very careful or you will scratch and scrape your truck bed paint and then what happens?
Rust happens! Rust is the beginning of the end to a good looking truck.
A spray on bedliner is probably the most popular form of bed liner. But there are very solid arguments for putting plastic bed liners in trucks instead of the spray on version or a roll on liner.
Plastic liners are tough. No matter how rough your hauling job, drop-in bed liners are made to withstand the roughest use. Take hauling concrete blocks as an example. Concrete blocks are going to scrape and scar your expensive spray in liner. Since the lining is permanent, a scarred up liner must be repaired or it just stays rough looking.
In contrast, a drop in truck bed liner is thicker than many other liners and virtually indestructible. And at less than half the cost of many spray on kinds, the plastic bed liner can be easily replaced if it's badly marred from heavy use.
The drop in truck bed liners come in one piece custom made to fit your bed. Some drop in bed liners are multiple pieces to fit the bottom and the sides again custom made for your truck. You get a perfect fit.
Since plastic is so tough, you can really use your truck to haul most anything with no fear of damaging your expensive ride. Don't worry, your truck bed is protected!
Think about dents too.
Those dents are what really do the damage. Scratches can easily be fixed. Dents not so much so. And a plastic liner is much more likely to absorb impacts that would otherwise produce serious dents in a truck bed. So it's dent prevention where the plastic liners really shine out the most!
And again, the plastic versions are cheap compared to most spray on liners. You can get a tougher liner for half the cost.
The drop in bed liners are custom fit and not available for many trucks. An alternative are rubbertruck bed mats if no plastic liner is available.
Water can collect under many liners and can be a place for rust to start. Make sure your bed can drain well if you use a drop-in bed liner.
If the liner is not well secured in place, it can move around and rub off paint from the bed. This again can be a start of corrosion.
Especially for pickups that do tough hauling jobs, a plastic liner is a great choice to protect your pickup bed from dents, scrapes and scratches.
