I left the newly applied white gloss to harden for a few days before sanding in preparation for the fourth coat.
This was predictably tedious but I took solace from knowing that I would probably only have to do it one more time, if all went well.
Here I am sanding the cockpit deck and footwell with a P280 grit. The blue tape is preventing the sander hose and cable from damaging the now pristine seatback tops.
The bright work light placed at right angles to the brush strokes clearly shows when the surface is flat and smooth.
When all surfaces were sanded I used a medium grit nylon pad to abrade the fillets and edges.
Everything was washed with water to remove paint dust, and wiped down with thinners immediately before painting.
The cockpit was now ready for more gloss, looking like this.
With previous coats I had some difficulty obtaining good coverage on edges and joins, so for the next coat I decided to roll over onto the adjoining face.
This is the port view of the footwell, seatback top and transom. Masking tape shows where to apply paint to cover edges.
I thinned the paint with 5% Epifanes Easy Flow, to improve flow and reduce brush marks.
I first painted the cockpit and forward deck well, using the 100mm ANZA brush for tipping out. See previous posts for more details.
It is certainly a fast way of tipping out fresh paint, but I found the brush's bristles clung together in spikes and created very noticeable brush strokes. Tram lines, in fact!
So the following day when I painted the topsides I used a soft 1" brush for tipping out. Here it is, with the roller.
It is a top quality synthetic brush. Very soft and supple.
I washed it in thinners when it stiffened with drying paint and started to drag.
It worked well and I was very pleased with the result.
This is the cockpit after gloss.
Here is a close up of the port quarter, showing how well this coat has covered and flowed on flat and curved surfaces.
As I always do now, I removed all masking tape while the gloss was still wet. I no longer keep it in place until painting is complete, because that leaves a pronounced step to the edge and often causes and hides flaws.
Here are the cockpit and transom skirt, all tape pulled.
I was really pleased with how things turned out. This is the port topsides. Nice and shiny.
I did not lose the wet edge once, and the brush marks are slight when using the 1" brush.
So I think I may have finally cracked the secret of how to get a good finish with a roller and brush.
In theory the fifth coat will be the last, so I will be extra vigilant and keep my fingers crossed!
The Epifanes product guide tells us to wet sand for the final coat with a P400 grit.
That won't be much fun, but I suppose it will have to be done... I will let the gloss get nice and hard before starting.
Onwards and upwards!
