Rust in the bed of my 2004. Ideas? and my repair so far.

I thought I would share this with you guys and get some opinions.

I bought my 2004 PreRunner used in 2007. No bedliner, mat, or anything just scratched paint. In the last year or so a few rust spots started popping up. I recently bought an undercover tonneau off of ebay and am going to add a Deezee bed mat next. I do not do any major hauling of anything very often at all. The bed of my truck is more or less a big trunk. Golf Clubs, Bat Bag, etc. I did not want or feel like I need to invest $500 in spray in nor do I fell confident in doing a Hercules myself.

All that being said, all I want to do is stop the rust from getting worse and clean up the rust that is there already.

Here is what I have done so far.

I bought the fiberglass rust removing pen pictured below from Frys Electronics for $5. This pen has been great. Great for touch up. All I am going to do now is put a little touch up paint over the areas that I have removed rust.

My questions are:

1. Any need to primer before touch up on these small areas?
2. Since the bed will only be getting wet now when I clean it (I will dry it out), I don't see a need to touch up all of the scratches, just the ones that have rust correct?
3. I would think a quick coat of wax over the existing scratches without rust once a year would keep the bed from rusting any further also correct?

Here are before and after results of 3 scratches before touch up paint and the pen.

 

to be honest touching up all of the scratches isnt going to do you alot. rust will continue to come through. rolling on or spraying on bedliner is easy as hell to do and is worth every penny,if you can sand and paint you can do it. i did mine in an afternoon and it cost me about 120$.

 

Herculine that junk

 

I agree that little paint pen isn't going to stop much. Just Line-X that bed man and be done with it.

 

I have/had a drop in liner, upon removal I saw some small rust spots in my bed. I'm gonna bite the bullet and Line-x the bed. At this point in time I don't think there is another alternative.
