Gelcoat is a super thick resin type paint that dries flexible and can be polished to a gloss.
its easy, mix the hardener with the paint, roll it on, brush it on, whatever, let dry, sand, repeat.
keep this process up until you have the desired coverage. buy PLENTY THROW AWAY ROLLERs, PAINTBRUSHES, PLASTIC BOWLS, RUBBER LATEX GLOVES, AND SAND PAPER.
It is like working with fiberglass, just colored. It dries slower too.
Many living in this generation shall never see the grave, JESUS gave us revelations and the time is very near. Dont be a soul that stands before GOD on judgment day and be told "depart from me, I do not know you".
REPENT, RECIEVE, REJOICE!!!
