I recently bought one of Eastwoods spray on bedliner guns for about $20. That thing works great!! I used it to coat my floor pans, trunk and trunk lid and most recently I used it to coat the underside of my floor pans and fender wells on my 1967 mustang. I about freaked when I pulled up the old carpet and insulation to find rust starting. I got the Idea here on shop talk a few months ago as a means to prevent rust and deaden sound. This gun was a great investment. A word of advice for those buying one. Get the one that has the attachment that will let you spray under things. I didn’t and wish I had. Also be sure you use a bed liner that is capable of withstanding heat. Some brands are only intended to take heat up to 120 degrees.
Good job Eastwood on a good product at a great price.
Thanks to all of you on shop talk. Keep the info comming.
