rusty bottom...

I've been researching POR 15 and undercoating for days and it looks amazing after its done..but really seems like a ton of work. Of you guys that have painted, did you disassemble or avoid anything specifically? Can I mess something up mechanically by painting it?

The wife masked off certain areas, and used a grumbacher artists fan brush for the majority of the work. It has a thin and flexible bristle so you can be accurate with it and get into hard to reach spots... Yes a TON of work!!

Just did a touch up on my rear axle and driveshaft with Krylon dual primer/paint gloss black spray. All I did was clean the area with soap and rag, sand with wire brush, and spray. Actually covered both areas with one can. I'll conjure up some pics later, but all in all it looks much better than it did!

I agree with the others. It's best to power wash the undercarriage to remove the road salt and dirt followed by a "paint" that converts rust into a primer coating. THEN cover with a coating of your choice. I have used the shaker can version of this stuff on patio furniture and it works very well.

Thats just non cancerous surface rust from exposed metal.

All undercarriage should be done in satin black. Gloss will turn dull looking after a while from road debris.

Kmart - Dutch boy Acrylic Enamel - Satin Black. Has to be from there...something different in there ****. Easy touchup. Seen alot of frames painted w that, looks good and its cheap.

This is exactly what started my entire project...if your like me, where do you stop. I should of just yanked the entire cab off the truck from the begenning.

Great thread. I too have been trying to fight the rust. It gets worse in the winters because of all of the salt and chemicals on the road for snow. I usually get under there and spray everything with Krylon rust protectant enamel, though I know all I am doing is covering up rust that is already there.

I guess I will have to look into the POR 15, or is it POR 30? I just know that every year I don't do it is another year I am going to stare at the underside of my truck and wish that I did.

Any learnings from those of you that have done this already are welcome as I plan for this in the near future.

It's POR 15, I don't think there is a 30...

Aside from what I wrote above, I fogot to mention, you need a good respirator mask, that stuff has a pretty strong smell!
