Posts: 83 You've pretty much answered your own question,,,
just treat like you would an automobile...
Auto bodyfiller,,, primer surfacer,,, sand/paint ...
You may be able to use AA for color but I think
I'd go automotive all the way here for base,,, then
the AA for any decorative graphics then a 2-stage
clearcoat to hold everything together ...
The reason I indicated AutoAir is most are into the
waterbase products now and automotive stuff tends
to be solvent base,,, ALWAYS WEAR A RESPERATOR !!!
Good Luck on it ...

Being at this for two months or less, I have AA Trans. No other paints yet and few of those. Still deciding and gathering goods. Just finishing a cart to set them on while working on them. They have set a while so it will be a long project. I figure I have time to sort things out.

for small nicks and scrapes
I would recommend a grinding tool to clean out the nick
and roughen the area within the nick.
Then apply fiberglass resin as a filler.
It will bond more securely and permanently with the glass.
(For larger fill areas, use some glass cloth pressed into the resin.
trick is to squeeze the resin completely thru the cloth.)

Glass resin can be sanded and smoothed/shaped to a finish.
Spot putty can be used to fine finish the surface.

in certain colour situations, there are colour additives you can get for the resin.
to help more closely match the original resin colour or gelcoat.

Glass and resin can be prepped and painted like any metal surface,
using just about any paint product.

Posts: 155 Feather the chip out. Get some gel coat and fill 'er in. Gel coat is a resin/glaze that you can mix to the same color. A lot of jet skiis are painted, which kinda makes a mess with gel coat, you'll just have to paint over it. Evercoat fiber fill/fiber glass bondo/kitty hair. Do not use regular palstic filler/bondo. Lord Fusor, duramix, SEM there are several that make an SMC repair kit. It could be a composite plastic which fiber glass resin won't stick to. Some of em you can just feather and prime. With cracks you'll definately want to use the Lord Fusor kit, and remember to repair both sides on a crack.

I have to disagree with Stang.
If the finish is not Gel coat, then why waste time with something that could be a little tricky.
Simple fiberglass resin and hardener is available at any Hardware or Auto supply,
is cheap and mistake proof really.
It will bond to anything (especially glass).
Even composites...I've used it on composite helmet material.
(unless there are some other products you have experience with)

Sorry Stang, but like me, you must have some experience with gelcoats, so I don't doubt that you have learned a process that would work, but I figured I'd keep it simpler for the less experienced. And getting into Gelcoats might be more than he needs.

I do however agree with not suggesting you grab "bondo" and start filling things!

Posts: 258 Most of these are scrapes and scratches from people putting things on the glass and pulling the stuff off, boxes, gas cans junk that should not have been put on there to start with. Quarter to half inch long scars to deep to sand out but not extensive. These have been well used by several kids at the river.

If I am going to go to the trouble to patch them up I would like for them to look right.

Posts: 155 In my opinion gel coat is easier to use then resin. Duraglass would be your best bet. The gel coat was an idea if the thing wasn't painted, then you wouldn't have to paint. I have to disagree with you Dave. Fiber glass resin won't work on the composite of a jet ski. It may appear to work for a helmet or whatever. If you get some big damage on a jet ski you'll be doin it over shortly after that thing hits the water. Been there done that. Steven might have to jump in on this one, living by a lake and all, workin on all them boats. Let's get it on!

Old Jet skis...
gotta be Gel coat(??)

so...I guess I must bow to Stang's suggestion.
yes, I may have jumped the gun, without thinking about Jet Skis.

if its just small scratches like that,
gel coat sounds like the better way to go.
You could colour match and paint it on with a small paintbrush.
(requires a hardener)
Then when dry, sand and smooth.
The gelcoat, if not over sanded, can actually be polished.


yeah, really, where's the boatman's opinion!??

Posts: 258 Thanks folks, took a good look and it is composite not glass. Checked with a couple places for the SMC kits. Not everyone carries them and a lot of places say do it just like glass. Guess they don't know the difference either. Thanks again. I'll keep looking.

Picked up some SMC resin. Now for the nephew to come around from time to time to put it on. As long as it is done by May it will be no problem.

Thanks again for the replies.

For fibergalss boat repairs: I like to use Duraglass, Gelcoat and West Systems. Scarey holes require matt or cloth and resin... and 4 hands. ;-) Also I will never again put auto paints on watercrraft. See If it's been screwed up...I probably screwed it up at least once.
