From time to time I get Pm'd from members who do low volume or hobby style builds.some i know as members here i have never met,others i have sprayed for in the past.Questions about tip size in the gun,what gun?How do I get yellow to not come out blotchy,you can see through it,etc.
So I figure a new thread is in order.
The problem one guy is having might be yours also,or learn how not to do something by what others are doing
So,how to make yellow cover.
On a multi colored job I save yellow for last.
It requires more finesse than most other colors.
They use a shitload of pigment just to get it to cover as well as it does,which isn't great.
All that pigment makes it heavy,which will lead to sagging if done at the recommended mil thickness.So you need to do two or three thin coats,letting it start to gel between.
You want to be stepping up the catalyst ratio as you go or you'll creep the shit out of it.
After,shoot another coat,yellow with a little white mixed in.This backup insures the final black back up for lamination doesn't affect the color.
I would advise a clear over(under when we're working in the mold)yellow that will be facing up to the sun.
Another note for you novice gelcoater/mold owners.
Pay close attention to the mfg date on the can,especially those "extra" cans from past projects.
Spraying a big boat in summer time with gel promoted for December is probably going to be a bad day.
So guys(you know who you are) ask away.
Edit***
I'm also getting Pm'd about gel repair and or total regel jobs.
This is not what I do.
My focus is on new in the mold gel and design with the mfg's.
For repairs and total regel you have many options including Islander,KMG,and others that specialize in this area.
You have other options as well.Lesser known but no less talented is Blas at Extreme Boat Repair in Lake Elsinore (951) 941-0043.
He was "the man" for repairs at Eliminator before the economy busted.Very talented guy.
Also,if you have a mfg in the area they can probably tackle just about anything you throw their way.
In Corona area,look to Lavey Craft.I have seen these guys do some amazing work,including regel as well as complete re spray in automotive paint.
Riverside and surrounding area look at Eliminator,nothing they can't do there.From small repairs to large refinish jobs.
Towards LA,Hallett.They have a Donzi in for a complete deck regel at the moment and extensive repair below the trim line.
