Mine are old and chalky and I want to clean them up in some way. Not sure if I should wash them in soap and water and a scrub brush or sand them lightly and paint them or how to tackle this job.

I had a pair that was very chalky I did not have much luck with sandpaper I did better with scraping with a razor blade to remove the dead layer. After you scrape all the dead stuff off you will want to coat it down with Penetrol. Penetrol is found at your local hardware store by the paints and thinners and such.

Penetrol made mine look like brand new as well, and it was very easy to wipe on. Just make sure to get all that chalky layer off first. You will beamazed with the results trust me! Mine were nasty and very pinkish/white now they look brand new.

Adding Penetrol to my list! Chalky pinkish is an exact description of my Z legs and I will be working on them today. I will try a wire wheel and scraping if necessary. They are pretty ugly right now but I think they can be brought back just like all the Teak that is beginning to look great with all the oil it now has.

Sand the Z-legs if you must but do not scrape or wire brush them; you will start to gouge the surface.

Penetrol can be applied directly over the chalkiness but the cleaner the surface, the better.

Remember, Penetrol will be a temporary solution; you may have to reapply a coat every year or two depending on exposure.

Like Tom said no wire brush! You will tear them apart with that.

I can not speak to any other experience other than mine but the chalky dead layer on the set I had was pretty thick. I did try to light sand then rough sand. It did not work until I scraped that dead layer off. Of course like when scraping paint you try to remove the top layer not dig into the surface.

Are you guys talking about the plastic z legs or the aluminum version

Plastic.

These things are ridiculously hard to clean! The photo below represents 2 hours of scrubbing, sanding, washing and scrapping. Fortunately they are only chalky on the outer, sun-beaten side but the chalk is extremely difficult to get off.

What seems to be working the best is soaking them in hot water and using a small pocket knife to do the scrapping. It does not gouge the plastic but will remove the dead surface if done carefully. I have used coarse sand paper and also did a spot check with acetone to see if this might loosen up the chalk. Nothing works well except the pocket knife followed by a good scrubbing with a dark red scotch brite pad.

There has to be an easier way but I sure can't find it! I did find the penetrol at the HD and will use it when I have them as good as I can get them.

I have had good luck WET sanding mine with #220, followed by #400. Anything finer than that won't cut it. Give it a try.

Just put Penetrol on them, no work, no fuss, they will look like new.

Yeah man that is to much work! Just get as much dust off as possible and then use the penetrol. That is all I did, and they came out incredible. I will warn you though you can use too much so wipe a little on at a time. Otherwise it will pool up and dry in blobs.

I just now finished the cleaning process and I did find something that was very helpful. Before I ever wet the second one I tried a spot of WD-40 on the chalk. It is the only stuff I found that cuts into the chalk and makes it easier to get off.

I will apply the Penetrol tonight after they are dry.

I just cleaned with soap and water, then penetral. Mine came out looking pretty good.

They look pretty good now after I got almost all the chalk off them and hit them with Penetrol.

Question on the Penetrol. I wiped it on and left it for 5 minutes according to the instructions for fiberglass and then wiped it off. Should I be leaving it on and letting it dry?

I wiped on then wiped off. I would think if you let it dry you would get a gummy buildup but I am not sure.

I searched and found this thread and it have me the decision to use penetrol. I cleaned them first, but wasn't about to use a razor blade but used pubertal anyway. Since there wasn't a good before after picture, I thought if add this picture to help out any one in the future. No scraping just apply and wipe off

Try using a bead blaster (preferably in a containment chamber) on a piece of similar, expendable plastic, using quick, short passes until you get the feel of the timing necessary to remove only the encrusted salt/soil/grime/algae/etc. without pitting or otherwise destroying the plastic. Then start on the Z legs with the same technique, then wash down with detergent, let dry thoroughly, then apply Penetrol or several coats of high-grade marine varnish. Good as new.

The process I used was to sand the legs first with 60 - 100 grit depending of how chalky they are. I sanded all the "Fuzz" off down to a good surface. I then apply a thin coating of a urethane by wiping it on with a cloth. This acts as a sealer encapsulating the fiberglass infused plastic. Give it 24 hours to dry and then sand it with 220. Reapply the urethane with a cloth, let cure and resand with 220. The final step is painting with Krylon Fusion paint (formulated for adhesion to plastic). I used Satin Espresso which was a perfect match to the OEM color and sheen. The standard Espresso is a little glossier if you wanted that.

I have done two sets like this. After 5 years the last set was still looking great.

check out the products sold by [url]www,auroramarine.com[url] they will have the right product for this and any other cleaning or re-furbishing plastic/rubber/fiber glass job on your boat. the stuff they sell is great and works watch their vids.
I'm not connected with them or work for them, I'm just a happy customer of many of their products over the past 7 years.

I just rejuvenated mine to what looks like new by saturating them with WD40, wiping down well with a rag, and then repeating. They were dry and produced the white chalky residue when touched before this, and now look and feel as if they just came out of their original mold. Was very easy process. Home Depot sells WD40 by the gallon

Hey Guys,

I'm in CA and cannot get Penetrol. What do you think is the best option to refinish my RPS legs?

Can you still get boiled linseed oil? There isn't much difference between that and Penetrol.

I use Krylon Fusion expresso color spray paint to refinish the plastic z-legs. I remove the legs from the deck and seat cushion. The legs look very good with a new coat of paint.
