So I have had my 1984 Hunter 27 for a year and a half. Last week when I was getting ready to wash her I found a nice brush deep in cockpit locker. We used it and I started to notice it was leaving a chalky residue. Being first time boat owner, I thought this great brush was removing some of the years of built up oxidation. I took the boat in for a bottom job and returned to it today and it has turned like a tie dye purple. I am now thinking that brush may have had a paint thinner type chemical or something on it. Who would put such a chemical on a long handled wash brush???? Anyway, I am hoping some one recognizes this look and can tell me what risk I run not fixing it ASAP or what would be the best fix financially. Not sure I have the time or facility to paint myself. I noticed the awl grip didn't seem to be affected. Maybe awl grip it all? My stuffing box started leaking like a sieve after the haul out and think most my money will go into having a drip less installed since I have serious access issues. The boat was splashed last night and by noon today I had about four inches of water in the cabin. This is supposed to be a 5 year learning boat, but the money I am sinking (literally) into it, might need to hold on a lot longer. Any advice much appreciated. I am sure I forgot this and that detail, but more than happy to provide more. Thanks in advance.

You may want to learn how to repack the shaft seal, not that hard. The packing dries out when the boat is hauled then leaks when it is splashed. Not expensive and part of the learning process.

The purple is interesting , you may want to try some Brite White tire cleaner in a small area and see if it makes it go away.

Thanks, I will possibly try the Brite White. As far as repacking, at 602/260 I can reach it, but not sure I can really do more than that. That is why I am considering having someone install the dripless. Maybe to save some money, I will pay someone to repack? But honestly with my size and flexibility, I would be retired before it's finished. Maybe I should take up yoga :redface:

What did the gel coat look like prior to the cleaning? Was it all chalky in the first place? If so, you might consider buffing out the finish or even wet sanding it. As with the other suggestion, you could try wet sanding a small area to see what happens.

It was very chalky white and I thought that is what was coming off. I think its weird it didn't damage the non-skid.:confused:

I guess my question would be for any fiberglass know it all's. If I don't do anything other that stare at this nightmare, will it cause any further damage.

The gelcoat pores are stained. TSP and bleach in a bucket of water will take it out.
Wet-sanding is a good idea after that, and it'll gloss up nice, but it's too much like work for me. ;)

Ditto with Joe, exactly what I was about to say. use a fine grit on the DA, and polish with compound first then gloss polish a couple of times. My stern looks great.

And don't even THINK about AwlGrip, unless you have plans to hang onto the boat for a LONG time.

The last quart I bought, with spray reducer and catalyst, ran $225.

Thanks Joe! Just want to clarify and not assume TSP is tri-sodium Phosphate all purpose cleaner??? If so, what ratio would I mix? Do I need to scrub with a brush? Then I think I will plan on wet sanding. I will do some more research on that :) Big thank you!

New GTU or GFO packing = ~ $20

Pint of Acetone and some clean rags = ~ $20.

Thanks Caleb, I agree with the packing. How to access it is the problem. Maybe an 8 year old with mechanic skills ?

The non skid looks like a different kind of paint, so it may have a completely different reaction entirely to UV, chemicals, etc. If you want the surface to be less susceptible to this problem, without repainting entirely I think maybe a little elbow grease will be necessary to remove gel coat down to the point where the surface can be buffed, polished and waxed. I wet sanded my deck, probably less aggressively than others might and the result is that I have a surface that is easier to keep clean.
Is this absolutely necessary? No, but I was embarrassed that people would sit on the foredeck and end up with a patch of white on their rear ends.

Are you close to a power plant? Depending on which way the wind blows soot gets into the oxidized geal coat. This is just one possibility but a wet sanding with 800 or 1000 grit paper will cure it then wax to apply a protective coat and then pretty soon just wax again. Just some of the fun of maintaining a boat.

A handful of phosphate in a couple gallons of water, plus maybe a half-cup of bleach. Use your rubber kitchen gloves, unless you have nicotine stains you'd like to get off.
I slop it on with a sponge, let it "soak", then give it a scrubbing with a deck brush. The oxidizing and "lifting" are chemical reactions, so vigorous scrubbing isn't necessary.

No active power plants but we are directly under the flight path of the Portland International Airport. The planes taking off fly directly over head. Interesting!

I used to sit under the Vancouver international airport runway and what a mess. Used Oxyclean in a bucket. Really works

I think Joe and Lost have solved my dilemma of the cost of Starbright hull cleaner. But man does it work! After an extended cruise on the river it took off the tannin stain in seconds with little scrubbing.
