No, but I've seen it done and it's now very commonly done. At the Arno Leopard factory I say them spray white gelcoat onto marine ply furniture then polish it and it looked like it had been cast in a perfect mould. A neighbour boat in Antibes recently had a scratch and scuff and the repairers sprayed gelcoat on the damged patch then polished it off to make a perfect repair. So it's pretty common technique

I want to do it too, and I hope by next Summer to manage it myself too
I know how to repair dings and scratches in a discreet level, but I want to push this to a better perfect level HOPE I MANAGE

I have seen small compressor with airbrush complete on Ebay £55.00

Anybody know if anygood ????????

they arent that easy to use. Maybe thats a bit unfair.. maybe I should say, there is a bit more skill than just switching on and squirting. And the smaller compressors are really for fine detail work, as otherwise the pressure drops, and then it all goes sour.
There are different airbrushes for different techniques, and then different nozzles for different brushes,and then you need to adjust it all to the "thickness" of the medium... and so on.
I doubt one of these small ones would be up t the job. A top brush can be £00's, for example, so maybe more a car type sprayer is whats needed.

Hi

I only have small areas to spray

I have stains on the rough gell coat so I cannot M3/TCut or sand

I will loose finish

That is why I want to spray

So looking for help !!!!!!!!!!!

I might be wrong, but I cant think that you can use gel like a spray paint, if thats what you are thinking. You can spray it, but only as a (skilled) method of building up a thickness-like several mm.
I guess you ve already tried the various stain removers, then, with no joy?

No! but I would be very surprised if an airbrush would spray GelCoat, Gelcoat is quite heavy and viscous and i would imagine there are limits to just how much it can be thinned. But then I could be wrong.

you can do it, but you have to double the hardner liquid to an extra 5%
you normally put 10% so you will have to go for 15%, the nozzle has to have also ticker holes

But that would make it cure much quicker an it already cures quite quickly. What Airbrush or maybe which airbrushes have ticker holes?

2.5 mm nozzle should do, according to my book
but some fiberglass resin shops can guide accordingly, for small jobs I would try the hands on pump as used in the video I linked above as it makes a less messy job IMO

Gel Coat or Flo Coat?

Robin

Gel coat with added wax can be sprayed and not need the air exclured with plastic sheet.

Just like flow coat, not sure if the ratio of resin to fillers is the same or the types of fillers used as it depends on the makers.

Last weekend tried Y10 and then Oxacil Acid but still no joy.

I am getting closer to spray by the minute.

I have had teak decking put on side gangways brilliant and stains gone

I still have a few on front deck but cost to teak a new boat cheaper.

I can get rid with 1200 but as said it is on rough gel coat and dont want to have patches of smooth bits on deck !!!!!!!!
