Hello all, first time posting been lurking and reading for a while now. I have a question regarding faded gelcoat on a 2000 23 ft Chapparal. Looking for advice on restoring the shine back to red gelcoat on this boat. The boat is actually my dads boat, he doesn't have time to use it anymore and it spent a couple summers baking in the sun and it's really taken a bad toll on it. I've buffed and waxed it to avail. I've heard of people possibly wet sanding and buffing. Is that likely the best route to take? I've done my fair share of wet sanding and buffing on cars in the past so thats not an issue. Other than there's alot of area to cover. Thanks in advance Ryan.

Re: Faded gel coat.

yeah, your right. You may be able to bring back the color by wet sanding and buffing. Big job though, I'd start with 600, then 1000. You'll get more ideas here. you have about 18 mils of gelcoat if its perfect, likely a bit more. The "hide" is probably 12 mils, so if you sand down to less than 12 mils you will start to see through it. Be careful.

Re: Faded gel coat.

Have you tried some of the polishes out there that remove oxidation? that would be my first step before sanding. Seeing as how you got the boat for free, maybe have a dealer do it.

Re: Faded gel coat.

I didn't get the boat for free(i wish i did though) lol. Anyhow, i've buffed the boat and hand polished 3 different times over last season and this season. It goes back to dull within a couple days. I'm pretty sure it's going to have to be sanded and buffed. I'd like to see if i could get someone local that could do it. As i really don't want to mess with it to be honest. I guess if i had some ideas of for sure what grit paper to use as wells as what compounds and style of buffing wheels others have used would probably be most helpful for me. Thanks for the quick replies thus far!!

I used woody wax restoring wax. Got ALL the oxidation off, but the upper, sun-beaten whitish areas just aren't that shiny "pop" white anymore...but my boat is also 22 years old.

Looking into it now, Which particular one did you use? I see there is a couple different styles etc.

Re: Faded gel coat.

I just used 1000 grit, then 1200. Followed with cheap Turtle Wax cutting compound and Meguire's polishing compound. It came out great -- went from light chalky pink to deep shiny red. No wax and a year later, it still looks like the day I did it -- except for a few new scratches.

It took me about 10 to 12 hours. I would use the 3M stuff next time. Probably could have done it a little quicker.

Re: Faded gel coat.

This is what I used. Woody Wax Brushes, Gloves, And Applicator Kits


I'd get a buffer. Apply by hand, change buffing pads frequently/wash frequently. I used about 80% of a small bottle on a 19' bowrider.

They also make marine rubbing compound. Can't really beat rubbing compound either.

You can see what was restored and what wasn't!

A lot of products out there......

Check into Aqua-buff. Get the 1000 compound and the 2000 polish. Apply with 2500rpm rotary buffer.

Best part of that product is it is water based -- so clean up is easy. Compounding a boat is messy with any product. Consider the clean up !

Forgot to mention -- I used a $29 HF buffer for the job.

+1, but mine was the $29 autozone buffer! Not impressed with it but the boat DOES look a lot better despite the crap equipment.

Re: Faded gel coat.

How much red? Red is one of the worst to try and keep shiny among the dark colors. Mine is blue above and below the rub rail. I go tired of buffing, and waxing. I finally had it painted with a urethane. No more compounding and waxing my a&s off.

This one has the red below the rubrail. The stripe is skinny up front and widens out towards the rear by the exhaust. It's not a ton of red but enough to try and get shined back up to be a pain.lol

Don't laugh but have you tried a buffing with Barkeepers Friend? It runs $2 can in the household cleaner aisle. It's amazing stuff.

We lightly cleaned the dark green on our '96 Chap and it made a huge difference. We also notice that water doesn't spot on that test area now either.

Re: Faded gel coat.

Ok, i got the Aqua-Buff stuff last week. Going to hit it tonight. Does anyone have the particulars on how they reccomend applying the compound? I have a good dewalt buffer. Ive read about possibly using wool pads and foam pads. And also wetting the pads or misting the area with water once the compund is spread on the boat? Thanks again for the replies and help!!

Going to move this over to Restoration. That's where the rest of the gelcoat gurus hang out.

Compound with a wool pad. More abrasive surface.
Polish with a foam pad - less abrasive designed for polishing.
Make sure you are at 2500RPM -- that is a medium-fast speed and where Aqua-Buff works well. Anything slower and you'll get compound swirls.

You'll find the compound is thick and harder to apply. That is what the water is for. Just a few spritz to lubricate the compound. After a while, the wool pad will be wet and you won't need any more water. But, there is not science to how much water -- just go for it you'll figure out the right amount as you work.

you'll also find that compounding will be messy. You are removing gell coat contaiminents and they'll sling all over. Aqua-buff is water based, so you can just hose away the mess and you work areas to see the results.

Take you time polishing. The polishing step doesn't seem like much is happening, but that is how you get the shiny look. Oh yeah, certain areas of the boat need more polishing than others. Like above water line side of boat, gunnels need to be polished the best. But top of boat areas where there is foot traffic or below water line areas don't need much.

When done, put on a good wax (I did use Mequires Marine Wax -- nice). And then it is just maintenance wax afer that. I used Lucas SlickMist. It is clear carnuba, spray on spray off stuff that did well.

Ok, get this job done and we need some before and after pics !
