A friend recommended spray on truck bed liner as being better to slow/stop the formation of rust, stating it was tougher than regular undercoating. I recently did some floor pan repairs on my Kelmark GT, used the bed liner on the inside. It is a lot tougher than rubberized undercoating, but it it better a sealing out the elements that cause rust ? Once I get the car off the ground a few inches I need to hit the underside, do I go with bed liner or undercoating ?
Thanks Steve
This is relevant to my interests as I was having this same debate with myself concerning floorpan repair on the way to work thia morning
Shake and shoot bedliner is crap in my opinion (I have sworn not to use it the last several times). Not durable. Now the stuff from a shop like Line-X, etc. is IMHO, tough.
Yep. Just tried it myself on a subwoofer enclosure. It sucks compared to raptor or under coating.
Truck is getting one or the other. Raptor kit less than a hundred dollars. But dont know the air compressor requirements for spraying it.
I know some are using the roller/brush type bedliner as undercoating. If prepped right it should hold up very well and double as sound/heat insulation.
