I have a 1994 Mastercraft Maristar 223VRS. It is fairly faded and has scratches on the side that aren't too bad but noticeable. Can this be restored completely? Or do I need to consider repainting it?

Best,

Yes, with reasonable care, gelcoat can be sanded with ultra-fine wet-r-dry sandpaper, compounded, polished and waxed to restore the luster. You can search here, TMC Search by Goo (http://www.google.com/coop/cse?cx=005775850323706454504:8-nmuizykqo)gle (http://www.google.com/coop/cse?cx=005775850323706454504:8-nmuizykqo) , I used the words "gelcoat restoration" and came up with these post that may help, http://www.google.com/cse?cx=005775850323706454504%3A8-nmuizykqo&ie=UTF-8&q=gelcoat+restoration&sa=Search

Buffing the gelcoat with an automotive buffer and compound (not the cheap random orbital waxers you see at the hardware store) is the way to go, not sanding. Same result (getting the oxidation off) but a lot less work and more consistent result. You can sand, or fill and sand, the deeper scratches. If you have scratches that are too deep to sand out, consider having them filled and repaired by a professional. Doing a good job on gelcoat is not a very rewarding job for someone as a first-time do-it-yourself project.

Note that you wouldn't be "RE-painting" it...you'd be putting paint over the gelcoat. Your boat doesn't have any paint on it now - paint and gelcoat are two completely different materials. Painting over gelcoat would require a LOT of gel coat prep work in order to get the paint to adhere. It would be FAR less work to remove the oxidation that's on there now.

Do a search here. There are some really excellent how-to threads.

Don't sand.

I spent a few weekends last winter with a rotary buffer and some Meguiar's #49 and #44 and eliminated my oxidation problems.

It's a bit of work, but sure does make it look purty.

You can do a lot with buffing. From what you say it sounds like you will be able to do a full restore with a good compounding and buffing. Check out my '85 Restoration thread here: http://www.mastercraft.com/teamtalk/showthread.php?t=19557&highlight=1985+restoration

That boat was done almost completely with buffing and I did not have to remove decals.. Only a couple of very small places actually required sanding.

All you need is:

Rotary Buffer
High Quality Wool Pads
3M Super Duty Compound
3M Perfect-It-II
High Quality Foam Pad
Your Favorite Carnuba Wax

I've had excellent results buffing my old Prostar as well. I did the entire hull in a weekend, less than 8 hours total. It was easy. Just make sure you get a high speed rotary buffer. Gel coat is pretty sturdy stuff and, unlike a car's finish, it would be pretty hard to screw it up with a buffer.

Good luck.

Shouldn't you be working on the 007 boat??? ;)

Had detailer do the work, but I had my 1993 190 wet sanded and buffed out with the decals removed and then they installed new decals.

Bottom line: it came out exactly as new. It was perfect.

You need a high speed circular (or "rotary") polisher like this one http://www.properboatcare.com/veprcipo.html to restore faded gel coat. Orbital buffers are only good for light polishing and waxing.



Here's what my old boat used to look like and then what it looked like after buffing it with the circular polisher and waxing by hand:

That is the way to do it. I plan on stripping down my boat next year and having this done by a guy that polishes all the custom high performane boats after they come out of the mold and before they rig them.

It is amazing when he is done with his work... the boat looks better than when it came out of the mold and every imperfection and blemish is gone. The guy I talked to is also going to take out some of the air bubble blems in the stern of my boat, left from the mold.

I'll say! Not only did he doa better job than I could have, he lifted the boat off the trailer and did the bottom. Easily the best $400 I ever spent.

$400? That sounds like its worth it if it gets the results you guys are talking about. I'd probably do something like before I put my boat up for sale to get top dollar. Got pics?

Did you have exhaust and teak stain build up under the platform on this boat? If so, how did you remove it?:confused:
