Monstaliner Roll-on Bedliner Paint
Updated: Jan 6, 2019
Next thing I wanted to do was to deal with and prevent body rust. I had a few spots coming through on the bottom of the body.
My game plan was to monstaline the bottom 25% of the van (monstaliner website). I really liked the monstaliner, it was a roll on application that I think anyone can do and make it look decent. Once all the rust was removed I felt like this would create a strong rust preventative barrier that would look good also without having to match factory paint.
First thing I did was pull off all of the plastics (mud flaps and wheel well trim). Secondly I sanded down and removed all the rust. I like an angle grinder with sanding discs, they are powerful though so be careful, but nothings better if you have to remove a lot of rust.
Once all the rust was removed I POR-15'ed the rust and bare metal and let that dry (good video of how to POR-15 a metal surface). I welded in metal pieces and used epoxy to seal up any rust holes that I punched through. I like PC-7 epoxy as it is less runny that most and is easily sand-able.
The welding and epoxy job didn't look great, but that is why I chose monstaliner, it wont really show the surface defects of my repairs due to the textured surface of it.
So once the POR-15 dried I taped off the area to be painted (very important to be precise and use GOOD painters tape). Once taped I sanded the entire area to be painted with a 180 grain sandpaper, cleaned it and then got ready to paint.
-Be ready to paint both coats within 10 hours. Once mixed its shelf life is 6-10hrs
-Buy extra rollers from them. The rollers make the textured pattern and if the roller gets damaged you will have a defect in your textured pattern (wont look good).
-Touch up with roller only, do not use a brush, it will ruin the pattern.
-Check temp and humidity
-When taping, tape inside the doors as well as you will be painting inside the doors.
-Prepare to paint inside doors and all trim and leave doors open to dry.
I let the first coat sit overnight and did not have a problem with it. Second coat went on fine and turned out well. I used the 1 gallon kit for the area shown per their recommendation and I think that was the perfect amount.
UPDATE: Here are some pictures of the van after a year or so. It has been holding up really well and although it tends to catch and hold on to dirt more than a glossy smooth finish it is really keeping the van in good shape.
