Gel coat Restorer


Recommended Posts

I just received 2 bottles of gelcoat restorer and last night I went to the boat and tried it in a small 2 x2 area. I had previously cleaned it with the recommended precleaner followed by rinsing. I applied a coat and I could not get it to look even. It dried quite a blatcy so am I not putting on enough product or too much. will it all even out with more coats. I used a good quality miocrocloth to apply it . the area is lightly oxidized so that is where I choice to start. Where do I go from here. thanks I love the products.

I had the same issue; perhaps someone can chime in and help with application technique. I emailed opt asking for the MSDS for this product and as it turns out, the product isn’t much more than bottled polyurethane; much like you would use to seal your deck. Pretty disappointing...

The SDS says it's "acrylic co-polymer"; I don't interpret that to be "polyurethane".  Did you use a scuff pad (Scotchbrite, etc.) before washing/degreasing thoroughly?

I used this product on some faded clearcoat and I thought it did pretty well considering it was an "off-label" use.  My advice, having never used this on gelcoat, is to make sure you remove any surface chalking, and the instructions say up to 4 coats may be required.  My guess would be that it's not absorbing evenly (and therefore being splotchy) because 1) you need to apply more product, either a heavier coat or more likely several applications, or 2) the surface is unevenly prepped, i.e. you need to scuff it better.

And...I'm sure this isn't going to be miracle product (nothing is), it's just supposed to be less work than sanding/polishing off all that dead surface layer.

It is NOT a miracle product (thanks Setec) and it has a learning curve.  As the attached video states, multiple coats are necessary to remove applicator marks and level.  It's important to remove the oxidized gelcoat, the reason for concentrated Power Clean AND scuff pad.

I was sent this file when I requested the SDS for GCR. It seems that I was provided the incorrect SDS by optimum customer service. Based on what I was provided, I incorrectly stated that GCR contained polyurethane. I stand corrected. Can you please send the correct SDS for me to review?
