Applying Gel Coat

There are 2 major ways of applying gel coat. Becuase it is a 2 part material you have approx 30 minute pot life. Spray in small batches up to 2 Quarts at a time.

line
"Hot Pot"your Gel Coat
This is a very effective and low cost way to shoot gel coat. However, you have to finish each batch you mix within approximately 30 minutes. In this system, a measured amount of catalyst is stirred by hand directly into a container (pressure pot) which is then sprayed from a pressure feed tank within the allowable gel time period.

Catalyst Injection System
High production Gel coat applications today use the catalyst injection system. This permits uninterrupted spraying. The drawback is that this system is more costly over $600.00. If you are interested please email us at Ask@Spraygunworld.com

Using a high quality professional sprayer will allow you to finish quickly with almost no sanding and buffing and create a spectacular shinny finish on your boat or watercraft.

Can you mix a finishing gun wit a Gel Gun.

line

Ideally no

Top coats and gel - The setups are too different and with both guns starting at $100 or so, it is not recommend you mix guns.

If you really want to mix gun for Touch Up work (we really don't recommend it for full coverage) then look here.

2 Gun Setups Here are some double gun setups

line
Touch up or Full Coverage or molds or Everything
line

We recommend a 2.0 or higher for gel coat. 1.8 is very thin and should be used only for quarter like repairs.

Anything larger than a quarter, opt for a 2.0 or larger

Full coverage on boats - 2.5-3.0 is recommended.

Large molds we have guns up to 7.5mm.

line

Gravity Feed or Pressure Pot?

line

Gravity feed is easy to use and clean up. The drawback is the smaller capacity. However it is a great choice for touch up work

For full size projects opt for a pressure gun. These are much more expensive so if budget is an issue, just fill your cup up more often and get a Gravity Feed Gun.

New 1 Liter pressure PPS system allows you to spray with the 1 liter on the gun or off the gun. It is a great option for those who want a quick system.
2 Quart systems are the norm. There are 2 quart systems with hard tupperware like disposable cups that run only about $2 each and are our favorite option for large boats. However, the pot is one of the best and most expensive we carry - of course...
