    ok guys...

    here's my delima...

    I'm sanding Insane Ewok down cuz it has a paint peeling problem, and I need to stop some surface rust as well as a bit of rott. some of it is sanded down to primer, and some is sanded down to metal.

    do I have to use etching primer, can I paint over top of the primer with a products such as zero rust? what is recommended here? after going through all this work I'm thinking of doing something that would look a little nicer, but I don't want to spend so much money I won't dare drive the thing.

    my original plan was to sand the entire thing down to metal, and spray the k5 with zero rust with some speed-liner on the rockers.

    my original plan was to spray the entire k5 with black zero rust, and to spray the mirrors, grills, bumpers, steps etc. all with black speed liner and call it darth blazer. I'm now debating on using a urethane one step or something else that would be fairly inexpensive?

    so what material options do I have to keep the costs at a minimal, and what are the advantages of each?

    Get rid of all the rust you can!!!!!!!!! If you have rust around the rear wheel wells you will have to cut out the inner well and grind it down or your paint is gonna bubble because it is rotting from the inside. This can also be the case in other areas like the rockers. To prevent further damage drill some holes in the back and spary in the aerosol style non rust, after that dries, do a rubberized undercoating and patch/plug the holes. Use Ortho on all the rust... apply and let it sit numerous times. Rust being called cancer is 100% true... it is hard to keep from coming back. After the ortho you should be ready to apply your POR or Zero rust. After that apply whatever primer that brand recomends over it. In terms of the bare metal areas... wipe it down with rubbing alcohol and then you can apply etching primer, just don't get the etching primer on any painted areas or it will bubble and look like crap. You could also use regular primer on the bare metal, just make sure your get it clean w/ alcohol or a paint prep spray. Use regular primer over eherything and get the truck smooth to the hand and eye. You may want to try different lighting and both dry and wet looks to make sure the surface is straight and ready. When it looks as good as new, spray your paint.

    What brand of Self-etching primer are you using? I use PG`s DP 40, with this product, there no messing around!! Strip the panel and sandblast all rust, removing it is better than hiding it, than apply 2 wet coats of DP primer, let it dry for 1 hour, sand out any imperfections, and I spray color the same day!!! I have found Epoxy primers hold back rust the longest, not products like POR 15!!! The nice thing about DP 40 is you don`t have to sand the primer (If coated before 24 hours), you can color coat without doing alot of sanding!!

    what would be the final cost for something like that??? (the DP-40?)

    I'm kinda thinkin of doing rustoleum against spots I have sanded that are sanded down to metal, and then doing a couple coats of primer. after that I think I'll go with epoxy primer as a top coat.

    over at stovebolt there is a guy that works for ZR... he's recommending I use that, and I think its cheaper then etching primer, and better product then rustoleum.

    If you buy a Quart of Dp is about $22, but it goes a long way! You also have a catylist that you have to mix in, that`s about the same price! What type of finish are you trying to get? Stock paint? On my trucks, they were stripped down to bare metal, rust was sandblasted, cut out if needed, body work was done, then I primed all bare metal w/DP, then after an hour, you have to let the primer dry, then I went over the DP with color, clear! With the NEW paint systems, were is not alot of messing around, epoxy(DP) is perfect for bare metal, this product will stick to anything and with the acids in the primer, it kills rust, if cleaded-up properly!!

    I just bought a spray can of the self etching primer and was planning on using it in the door jam area. I sand blasted all surface rust and feathered the paint accordingly. Will the self etching primer affect the original truck paint?

    No, It shouldn`t hurt the old finish, but put medium coats on just in case!! A real wet coat could lift the old paint!!!

    actually I'm using epoxy as my top coat... black and I'm still going with the darth blazer idea. I'm sanding my topper down, and painting it also. I think I may do it with speed liner though.
