Glass-Like finish without resin?

[dialup]

I am looking to get a glass-like finish over an acrylic painting on canvas. It is 4ft x 4ft and. I have used polyester resin in the past and it has worked pretty well but becomes pricey and when there is an issue, it is VERY difficult to overcome. I have also tried pouring medium with somewhat success other than it doesn't want to self-level on such a large surface area. Does anyone have any advice or a direction which they could point me?

Acrylic clear high gloss spray by Krylon. Three to four light thin sprays should do it. Go to fineartamerica.com. Look up artist carl owen. open the abstract gallery and click on Earth's Heart III. You will see what I mean. Be sure you lay your painting flat and spray it in the sunlight so you can see where the high gloss hits. Hope this helps you.
