Oxidized Gelcoat. Best way to repair question.

Re: Oxidized Gelcoat. Best way to repair question.

Pics of what YD? You can see plenty of pics in my refurb thread. Also, I have thrown the wet sanding to the wayside, I am dry sanding with film discs, much easier and beautiful finish. Just take a look at my bottom restore in my thread. All dry sanded after scraping paint off.

YD, Isn't the clear over the colored gelcoat with flake just a clear gelcoat?

Re: Oxidized Gelcoat. Best way to repair question.

i will get some pictures when it quits raining. It will probably be after work on Thursday before I can get them. I have a small repair question that I need to ask once I have pictures posted.

Thanks for the help,
Brad

Here are a few pics if you are interested of what I started with, Pink,

Tried a foam buffing pad on 7in. buffer and 3M compound with wax. Improvement but still bleached beneath, pics dont show it.

1st stage of 600 grit wet sanding, leaves los of scratches but the product I'm using accounts for that.

This next one is more thoroughly wet sanded, all by hand, but the only part that has Poly Glo on it is a 2 foot section above rub rail. That is one coat and it calls for six. You can pick it out.

Will have more close ups to share by the weekend.

Re: Oxidized Gelcoat. Best way to repair question.

every one wet sands....

i personally am not a big fan of it.

you cannot remove 400 wet scratches.

dry,,,,no problem.

dry all the way to 1500.

over 1500 is a waste of effort......your standard lambs wool buffer at 3000 sands at 1750 grit

True..

Are you suggesting members Dry sand up to 1500 ? ..

What..on a DA ?? or Hand ??

Wet sanding is Bogus now ??

over 1500 is a waste of effort......your standard lambs wool buffer at 3000 sands at 1750 grit

Anything close to 1k is overkill on gel .. 600 wet is fine. .. You can sweep over 600 lightly then buff it out ( Gelcoat..not Paint..) .

im not looking to argue with you.

i said im not a big fan of wet sanding however yes,...i do it on darks.
and yes.,..i dry all the way to 1500...on white or light.

what the owners of thier boats do, and how they do it ...is up to them.
some like wet sanding....some dont...this thread has three different ways to do it...they can pick what ever way the feel comfortable with...
its just sanding gell to a finish.....it wont sink them.

Re: Oxidized Gelcoat. Best way to repair question.

Well thats why this forum is great, different point of veiws and experience.

I personally would never try and wet sand or dry sand by hand or by da sander with 600 and then buff out and call it a day. Your leaving to many scratches in the gel that the compound will fill but probably won't get rid of.

You need to atleast go to 1000 imo and like OOPS said higher and wet on dark colors works great.

Not sure what type of disks you guys are using but the film discs imo is the way to go regardless. On a light color, 1000 on a da is plenty with the da sander.

If you are going to dry sand, get the film disks, I use Indasa Rhino discs. half the price of 3m.

Ditto ..

Sorry.. I did NOT mean to come across that way mate..

I was asking some simple questions regarding your post on Dry sanding up to 1500.. You never specified if it was Machine or by hand. I thought it was a good question that you might be able to clear up.

Again I am not very good at explaining myself sometimes on Posts.. my bad.

i said im not a big fan of wet sanding however yes,...i do it on darks.
and yes.,..i dry all the way to 1500...on white or light.

That was the reason for my post ... to clear up any misnomers of what you were suggesting.
Nobody likes to wet sand .. but You agree that sometimes it is better then dry/hand or even dry/Machine. .

what the owners of thier boats do, and how they do it ...is up to them.
some like wet sanding....some dont...this thread has three different ways to do it...they can pick what ever way the feel comfortable with...
its just sanding gell to a finish.....it wont sink them.

I agree.

All I was suggesting is that the OP has a Metal Flake boat .. NO pics..asking suggestions..

Metal Flake and a DA is risky IMO.. your sanding Clear.

Again..most times you can polish out Gel. But if your dealing with a Clearcoat then it Might just Might be best to take it slow with some Wet Sanding instead of a power sander.

That was the reason for the "wetsanding is bogus now" comment. Because Each project is different IMHO..

I await some pics and updates from the OP ..

YD.
