Recent experiences with MiniCraft aerosol gelcoat

I feel compelled to describe my recent experiences with the aerosol gelcoat manufactured by MiniCraft in Florida.
I am in the process of restoring my 1964 Sakonnet and have ground out four areas of gel coat, varying in size between 8 and 80 square inches. I have been using Spectrum Color gel coat from a quart can for repairs so far with decent results. I decided I'd take a shot with the aerosol product from MiniCarft to see if it were any better/easier than the Spectrum gelcoat I'd been applying with a brush.
After trying this stuff out today on the boat, the answer is a resounding NO! While I appreciate the idea and intention of aerosol gel coat, this stuff is horrible. You have to inject the MEK catalyst into the can with their little plastic pump ($29). You then are obligated to use the entire contents of the can within 20 hours.
So with all my areas prepped and masked, I injected the required amount of catalyst with my $29 plastic pump which promptly fell apart after I used it, shook the can for a minute and began to apply the gelcoat to the smallest of my prepared areas.
The gel coat sagged and ran and was pretty much useless. I wiped the area clean and tried it again after more shaking. Same results. I am disgusted with this product and heartily disuade anyone from falling for what I feel is largely a 'gimmick.'

Justin; Thanks for the update. It came at a great time for me. Good Luck on your Sakonnet! I've a '61 Nauset I hope to get turned upright (after epoxy coating below the waterline) and have a bit of "blue" to patch. Thanks again! gary

I also tried the minicraft product and had much different results. Mine worked very well. Also, my instruction sheet differs from yours. The product must be used in 4 hours not 20. Also, you must shake the can a minimum of 3 minutes both before and after you inject the MEK. Your sagging may have been because you put it on to thick. I sprayed a thin coat. And my pump survived the process very well. Sorry to hear about your results but I wanted others to know about my success with the product. I loved it!
