I bought this sweet Wildernest camper from a dude in flag on Craigslist. It needed a lot of work. (Still does) as I figure out how to repair stuff and put it back together, I'll share instructables on how to make your Wildernest (or other truck camper) looking awesome so you can camp with your family or pull down some climbing birds at Yosemite.
Step 1: I Hate Raw Fibreglass
I've always hated how sprayed glass fibre in resin looks. I've also hated the bumpiness. The Wildernest I picked up had some staining and s**t on it too. You might be able to notice my truck bed has been lined with sprayed on hot polyuria. It's awesome stuff. I wanted my truck cap inside to match too!
First thing you need to do is wash it all really good. Like. Really good. Grease, rust and other smeg will really roger everything else up.
Step 2: Tape Up Everything You Don't Want to Coat
This is important:
1) DONT USE BLUE PAINTERS TAPE.
It sucks. It doesn't stick and let's paint creep under. You can use something like frog tape... Which actually works, or just use good 3m tape. Make sure it's a new roll. Not something you've got laying around. Also. Make sure it's got plastic on it when you buy it from the store. Air is tape's #1 enemy.
2) buy the green tinted paper
It will keep paint from seeping through the pores of the paper and staining whatever you've masked.
3) wear a mask. Not a dust mask. A carbon filtered painting mask. This paint I'm gonna tell you to use is not friendly.
(As you may be able to tell. I taped it up fast and dirty to take this pic. A tape and paper machine would help you make it a nicer job.)
Step 3: Get You Some of This Magic Ish.
It doesn't leave the exact same texture as that of a industrially sprayed on bed liner... But it makes a nice rubbery surface!!!
Step 4: Spray and Pray
Um. So you know that painting mask I told you to have earlier on in this instructable? USE IT!!
This sprayed on Bedliner stuff has a HUGE spray tip on it and it sends particles EVERYWHERE. It's got a 12/12 tip or something 12 inch circle at about a foot away. (It's a special magically engineered tip that is metric too- 12 cm away it's 12 cm across) ;)
Start spraying. I needed two coats on many places to get full coverage and I needed 2 cans to do the inside surfaces of my Wildernest (including the bed area)
Now the inside of your truck camper looks like an awesome love shack!
