SEM Pro-Tex bed liner questions

I'm just about to buy a kit of SEM Pro-Tex bed liner. The kit doesn't come with a gun.

I still have the GEO gun I got from Barry. Can I use that for spraying the Pro-Tex?

Also, in the instructions for Pro-Tex, it says it can be sprayed over epoxy but it must be cured and sanded with 180. Can I get good adhesion if I spray the SPI epoxy one day and then the Pro-Tex the next day with no sanding? Or should I just do what SEM recommends?
 
Results follow up:

SEM Pro-Tex tintable version. Tinted with Pro-Spray tint in RAL-6009 Fir Green to match the single-stage color on the truck.

I sprayed it all yesterday morning. I was out there before 6AM.
There were warning labels packed in the bed-liner box about spraying it in hot, humid conditions which is exactly what we had been having. Pot life is severely reduced and flash times have to be well longer.
So, I put the bed-liner cans in cool water overnight and started early. It worked out perfect. Normal flash times are 20 minutes but because the humidity was 90%, I gave each coat an hour.

Because the whole prepare process took me longer to do than I had figured and it was getting later in the recoat window of the SPI epoxy, I decided to scuff it all with 180 sandpaper just to make sure I'd get good adhesion. Here's my photos before starting:

Photos after removing the all the masking. The directions have you unmask as soon as the final coat is complete.

This SEM Pro-Tex is good stuff. I'm impressed. Because the kit had 6 sprayable quarts I knew I should have plenty since I wasn't doing a bed floor. I had enough for 3 coats of everything. It called for 2 to 3 coats and you have full-coverage by the second coat.
It sprays easy and is easy to make it look just like you want with how heavy you put it on and how close you hold the gun. I backed the distance off and went a little lighter on the last coat to give it a little more rough look. If a person wanted it to look more smooth, it would be easy to do but I liked it better a little on the rough side.

I think the color came out just great too and my wife (truck is for her) is extremely pleased with the whole look.

Next I will work towards getting the bed painted so I can mount it on the truck and get the room back to work on the paint prep for the fenders, doors and hood.
 
Awesome job Roger, looks really nice. Does the Sem Pro have UV Protection?

Thanks.
I didn't even think to ask that question. Just looked and all it says is "resists fading". Isn't that a function of the tint? I don't know.
This truck will be parked in a garage but be used for normal errands. So, it will see some parking in the sun some but not extended times. It might see sun all day a couple of times a year at outdoor car shows.
 
From the pictures it hard for me to tell if the edges on those running boards is stock or have you done something custom to them?

Nope. All stock.

The cab steps were replaced with reproductions but they are installed as original. The bed steps are original parts as are both bed sides. The bed front and tailgate are reproductions from MAR-K.
 
I think I like this a lot better than the rock-it liner.. The rock-it is good for wheel wells, frame rails and things like that,, but it's a smaller kit and doesn't seem to go nearly as far.
 
Thanks guys.

Here's the photos after completing the paint.
I probably did this opposite of how most would do it in that I sprayed the bed liner before spraying the paint. As I was taping, I was a little worried that I may not get a good tape seal but, I used the 3M extra sticky green tape and pressed it down firmly on the edge. I didn't have any issues with bleeding.

In the photos, the bed liner appears a lighter color than the paint. It's looks just like the photos in person too. However, most of that is the way the textured surface catches the light. In indirect lighting, the colors match extremely well. Since part A of the bed liner is kind of milky looking before adding the tint, the color might be just a touch lighter but not much. I have no complaint about this whatsoever. I'm 100% happy and my wife is thrilled. She picked all the colors for her truck (with my input but she made the final decisions). I just wanted to make these comments in case you guys were thinking about that.

The bed wood is just in their for a trial fit. No problems there. I was thinking about a sealer and SPI Universal Clear for them but I think I'm going to use the Watco exterior natural oil finish instead. It's just to easy to apply and re-apply when necessary for a truck that's going to be used. For a show truck with oak, I would go the clear route though.

Stick on letters. Way easier that painting. Look perfect too,

Nice color selection. I really like the wheel contrast. Refreshing not to see some aftermarkets on it.

I bet you were hesitant to shoot that brown at first. Out of the can it looks like Hershey squirts but sprayed out it looks nice

What brake pedal relocation kit did you use? I have a 59' GMC shop truck and the one I used from Ebay wasn't very good.
