thanks for sharing surf city

what size spray gun tip have YOU found best for gelcoat

it seems people use pretty much everything from 1.4mm up to 2.3mm

as in this google find

* Gelcoat is quite viscous and almost impossible to spray without thinning it. The less you can thin it the better the gelcoat will be, so the use of a larger spray tip is required. I use both 2mm & 2.2 mm HVLP gravity feed cup guns for most of my heavy shoots. At this size the thinning is kept to a minimum.
