Let us know how this works out. I think you'll have to thin that glecoat quite a bit to get it to go through that sprayer.

Is it the same consistency as the little jars of repair kit gelcoat? Those were like peanut butter.

For years the only gelcoat sold by Whaler was in pint paint cans, and it had the consistency of paint. Totally liquid. I think the paste repair stuff is only recent, and in the small jars.

Wow, you got hammered! I sell Spectrum and never have charged that much!! By the way the 2 oz jars are for gouges and scratches not spraying!! When applied with a spreader the paste works great. Prevals do work, Jim is correct is advicing to reduce properly. Make sure you have "Surface Seal" or "Wax" otherwise the gelcoat will stay tacky. I wouldn't suggest spraying a whole interior with a Preval.

Have fun wet sanding and buffing!!

As was mentioned you won't be able to do the whole banana with what basically is a touch up spray bottle -- your going to need a regular compressor spray gun or a HVLP unit with the proper tip -- good luck --- play it safe with necessary precautions

I sprayed Spectrum gel coat last fall with a Preval sprayer and did not feel it had enough power. I later tried a Royal brand disposable sprayer and was really pleased with its performance.

See this thread:

Regarding the non-skid area, don't worry about it, it's non skid and a little orange peel won't matter.

I'm in the process of repairing a 13' BW (1979) and bought a quart of "desert tan" gel coat from Spectrum Color. I had contacted Spectrum Color and they had recommended the quart can (with a consistency of paint) for spraying and yes, it is expensive. My first two attempts at spraying the gel coat with a Preval sprayer were unsuccessful. I did not thin out the gel coat enough with acetone. On my third attempt, I first filled the sprayer with the gel coat, added acetone and tested the sprayer. I repeated adding additional acetone until I had a good spray coming from the sprayer. Once this was accomplished, I then added the surface agent and catayst at the recommended amounts (provided by Spectrum)and applied the gel coat ---- success! The color match was great and the texture of the gel coat application required minor wet sanding.

Thought I would jump in here...I just repaired my gelcoat with minicraft aerosol spray gelkote. Stuff is awsome! A bit expensive to start with the color match and all. Costs $55 for the color match, $25 for the MEKT pump and $25 for the can of product. If you need more, they keep your color on file and its only $25 a can after that. One can covers about 10 sq feet. Goes on like spraypaint. Wax already added. The pump is used to put the hardener in the can. Load the can with the hardener, remove the pump and put on the nozzle, shake it up and go! You end up with a orange peel finish and have to wet sand and buff. The color match on my boat was right on! I am very pleased with the results! check it out

Wonder the real scoop is on this minicraft stuff? Guess it depends on the user's skill. See also post last dated 4/17/01!
