Rocker Panel Texture Touch-Up

[Karl_W911]

I had a small pinky-finger size exposed spot with surface rust when I bought my car. I decided to sand the spot down today and thankfully, it was the lightest surface rust I've ever seen. Porsche does a really good job with rust protection!!

I'd like to now touch it up, but I don't want to repaint the entire panel as the surface rust was only in that one spot, and even if there is some slight peeling paint(I peeled it back some myself to check if the surface rust had spread under the paint) in that spot. Having a seamless match isn't a concern either because of the location of the spot, but what type of textured coating would I use for that spot?

Wurth Body Schutz is old school but I would prep it and see if a truck bed liner shop could squirt the spot.

Not sure bed liner is a good idea as I'm not sure you can paint it. Years ago I needed to match the pebble texture on the deck of my sail boat. I used a bit of latex laid over another part of the deck to make a mold of the texture. I then poured a small amount of body filler into the mold and pressed the latex and body filler over the area to be fixed and pressed it flat with a book (or some other tool). After it set up, simply pull the latex off and spray it with primer and then paint. Easy.

I hate this textured protectant on my 944. I have several areas where it has cracked through and is promoting rust. I keep meaning to try to dissolve it and fix the rust.

Not sure what will remove it, and if I would want to replace it.

You can scrape it off (it's thick) but it's a job. Be careful using sharp blades to do it.

I took it off my '87, prepped a couple of nicked / surface rusted spots that were hiding underneath and applied POR15 - just left it black. Looks fine.

There is a product from SEM that is a pebble texture rocker panel guard. The process I found for to work on my car was to sand the original finish pretty much flat across its texture and then tape off the shot line on the rocker panel between the ground and the door to give you that sharp level look, tape off anything else you don't want over spray on cuz it does have a little over spray. Shoot the product from about 12 to 14 inches away it will leave a texture. let it sit for about 20 minutes then remove the tape by pulling it back over itself at a 45 deg angle while it is still damp to give you that really nice level line and then do not touch the product for at least 3 hours. This material can then be primed and painted the original color of the car or the color that you desire. The product when it comes out of the can is a clear to opaque color. If you have any questions about this process you can PM me and I will go into it further.

I'd seal the paint with Wurth Metal Prep, which will put a phosphorous layer on the bare metal, then Wurth Rust Guard, a great primer, or something like it. Follow with the Wurth Stone Guard, maybe apply it with a small brush like a solder brush, you can get good texture and lap to the existing pebble texture nicely. Paint over the stone guard.

When doing spot repairs like this, the product you use is less important than the care and technique you apply. There are lots of great products out there, I happen to use Wurth.

I hate body work with a passion, just slightly less than I hate corrosion, so ymmv. Good luck!

1st the 944 bodied cars were not painted by Porsche !
they were built in the VW / audi plants .

to repair what your looking at is very ez to do .
personally I do not like pray can products at all but in this case they will be fine for this job .
you would spot in the bare metal area with some etch primer one or two light coats is all you want .
then let it dry and sand it lightly with a red scuff pad . wipe it off with a tack rag and then using transtar texcoat chip guard (spray can) spray on 2 or 3 coats and blend it out into the rest of the chip guard on the panel . (mask off the chip guard line on the fender )
let it dry then again sand it lightly with a red scuff pad and again wipe it with a tack cloth and the spray your body color .
the sharp edge of the chip guard on the panel you will want to feather edge out as you don't see it after your all done with the repair .

as for bed liner to use as chip guard is not a good idea at all !
the two products are totally different and made for different things . bed liner is a hard product and being such it doesn't take sand blasting from your wheels very well .
chip guard is a more rubbery product and is so for that reason .

I've decided with all the touch up I'd have to do, I might as well repaint the panels when I've got the time, shouldn't be too hard.
