Changing colour of gelcoat question

That would work. Thanks, Scott. Much more affordable.

The key will be prep.....

You will need the entire boat sanded and ready. Hang the boat from the transom and bow eyes.

Spray as much of the boat in one shot that you can so you do not waste product by cleaning the gun.

Spray everything from the rub rail down, then the cap from the rub rail up

Then spray the interior

Thanks for the steps.
Sides are sanded, just have to fair the bottom and the cap.

To catalyze the Duratec and gelcoat, do I add MEKP for the volume of the gel only or the entire volume?
I just went to the Duratec site. I downloaded the instructions. Google is my friend.....lol

 

[Scott Danforth]

Entire volume. 1.5% is what I target

Ok, Thanks Scott. I am jumping the gun a bit, but I will shoot the Cobalt blue gel I have on hand today. I will gelcoat the sides for a test to see if I like it.

 

[carlos515]

Shot a test side. I wiped the sides down with acetone, yet I still got fish eye. Will sand and re wipe with wax and grease remover.

If you are not using a desiccant filter and water filter on the air line , you may be spraying the oil from the hose.

I have my air dryer on. It has water, oil and particulate filters, then after the regulator I have more filters. I think I should have used my Proform wax and grease remover. Or I very likely missed some spots.

 

[carlos515]

Well..... I washed the other side down with wax and grease remover. Same fish eye. Would too old of Duratec do this? My sealed can was 2.5 years old.
I ordered a new air line just to be on the safe side.....never used this line for painting before.

To answer my own question....Duratec 904-001 has a shelf life of 6 months.
I will be ordering a new gallon......
