Weird Gelcoat situation... need advice

Hey all,

Fairly new here, so many of you don't know me that well yet, but I am nearing the end of a rebuild on a 1985 Riviera Bowrider...

I am at the point of spraying the gelcoat, but something kind of strange has happened...

I am using the cheapest evercoat non-waxed (laminating) gelcoat I can find... (long story), but suffice it to say I don't want to put another penny into this thing that I dont have to..

Well I have sprayed the cap on the boat, and from my understanding this type of gel coat requires a PVA Mold release in order for it to fully cure to a shiny finish...

Well I simply sprayed it on, and let it sit outside (FL Sun), and it has cured to a hard shiny finish without using any type of mold release... ???

I am using the gelcoat, about 25% acetone to cut it for spraying, (yes I know max is supposed to be 15%, but it wont spray still being that thick), and added the exact amount of hardener for my tempurature range..

My questions then are the following:

1. Do I need to do anything else to the finish the final coat other than wax it?
(Like I said the finish looks ok to me??)
2. Should I own up and go ahead and buy the waxed type and spray another coat? (I really really dont want to spend another 200 bucks on gelcoat)...
3. I have read a lot of information, and it seems a lot of people wet sand to a certain grit (600-1500) depending on the gelcoat, then rub, polish, wax... if I am happy with how my gelcoat looks as is... is this a "Required" step? (I absolutely do not want to sand this whole boat if I don't have to)
4. Most importantly, Will leaving it "AS IS" cause me any kind of problems down the road???

Reason I ask is, my son's birthday is in 3 weeks, and I want this boat ON THE WATER by then... I really do not have the time to sand down the gelcoat with fine grit, polish it and all that other stuff... Been working on this 2 years already...

However, the boat right now is currently apart (cap off, engine off, etc) and if I were to do it, now would be the time, as I can flip the hull, etc.

I know thats kind of a lot of info and a bit of a confusing mess (sorry), but any help or advice would be appreciated...

I am just really confused, because my gelcoat isnt doing what its "supposed" to, and the net result looks like I may be able to skip a lot of the work... which is certainly fine by me!

Also keep in mind, This is just a small runabout im eventually giving to my son when he's old enough, and I am sure he will be beating on it at that time. :)

A picture would help, but I am inclined to say that if it isn't tacky at all and the finish looks good, just wax it and consider yourself lucky.

Yeah I tried to take a picture, but its too bright/reflective and I can't get it to come out ...

Thats why the long description...

Basically its hard, shiny and Im ok with it, but my concern was it seemed like there should be more to it than just spray it on and be done with it...

I just dont want it coming off a year down the road if you know what i mean...

Its not as super shiny as a brand new boat, but for me and this boat its fine IMO... so you think I would be ok to just wax it and go?

I'm no expert but I can certainly buff gelcoat to a nice finish if I am so inclined.

Your finish will not be like a factory finish without being polished up. Even out of the molds, the factories still polish the gelcoat.

As to durability, it is either going to last or it isn't only time will tell. A coat of wax will definitely help to protect it.

It is hard and shiny and smooth-sounds like you did a good job. Enjoy.
