Sam, Me thunks it's about time You Jumpz Feetz Over Headz into a GelCoatz Job!!!! You needz to havz dat in yerz toolz Box!!!!
Ifn' I'm every BRAVEZ enuf to dooz anuterz Boatz I'z gunna GELZKotz it!!!! After I pour Boiled LInseed Oil ALL over every inch of the Wood and Drill me a BUNCH of HOLES in DA TRANSOM!!!!!!!!
The reason for the Pot gun I THINK is...It holds 64 oz of Gelcoat. That gives you a LOT more product to lay down before needing to stop and clean out. As noted, You want to keep a wet edge and with Gelcoat and cleanup and re-loads that can be tricky if you're NOT set up properly to get it done in a timely fashion. Most Gravity feed cups are 32 oz at the most. They do now have the disposable plastic cups so that makes it a bit easier to make quick reloads. A small bucket of acetone to dip the gun in and brush it off and then shoot some thru then screw on another cup and load it up. Can be done in a few minutes. With a helper shouldn't be much of an issue. I HAVE a 2.5 TCP Global Gavity Feed HVLP gun just waiting for a GelCoat job. Guess what the tip WILL fit on the HF Cheapo Guns too!!! Let me know if you want me to Mail you the nozzle so you can try it out.
