I have had two spray in liners, and I love them. First of
all, the drop in liners are slick and the bed of your truck will rust
underneath the liner due to the constant rubbing of the paint. Also, if you
have a goose neck plate in the bad and also haul shavings, if you use a drop
in liner, the shavings will get in-between the liner and the bed and hold
water, thus more rust. I tried one of the do-it-yourself kits on the
running boards on my horse trailer, and it is not as durable. For the
difference in $$$, go pay some one to spray it for
you.
