I got an older Anschau Komet trailer that needs some care and decided to repaint the entire top side, which is white painted fiberglass. What paint would you recommend for doing this? I'd like it to be a bit glossy and waterproof, as the trailer will stay outside in summer but hangared in winter.. Thanks!

I repainted one fiberglass trailer with Benjamin Moore gloss exterior latex house paint. Sprayed it with an HVLP sprayer. Looks fine, but has a little more "orange peel" texture than I would like due to not thinning the paint enough. Should have rolled it on. Note that it will blister if you trap moisture against it (like putting a tarp over it). Otherwise, it seems to be holding up very well.

Any of a number of quality "topside" boat paints are suitable. There are single part topside paints that are designed to be rolled on (or may be sprayed on). The advantage to roll on application

Probably the best compromise of cost/quality is to sand/repair as necessary and then take it to an automotive paint shop and let them spray a polyurethane based paint. Seen that done a few times on glider trailers with excellent results.

On my Komet I did a light sanding with a disc sander and then rolled on white house paint from Ace Hardware. It was a combo primer/paint, cant remember the brand. Still looks good a couple years later. I figured houses sit out in the sun all the time and the paint holds up pretty well

We have used reflective roof coatings such as Kool Seal. Seals up any
minor leaks and also reduces the temperature inside the trailer.

I refinished a Komet trailer 3 yrs ago with Boat paint . Self leveled and didn't see any roller marks afterwards. Came out great, UV protection as well although about $50.00 a Qt. I sanded first with an orbital sander 150 and used 5 coats .
Very good coverage for a qt.
Also afterwards I used a white roofing silicone along the galvanized base .

What's a Qt if I may ask? Or is that in liters? (I'm from EU)

I painted my trailer with HC-2500 Amerflint II polyurethane from Tamco paint. It's been in sun and snow year around for 3 years and still looks like it did the day I painted it. It's excellent...I'm painting my glider with it this month.

Excellent customer service, too.

I used Lesonal 540 2K primer. Great stuff, not cheap but the base coating is really good.
Available in Europe, from AKZO I believe.
Next step is to finish the final layer in gloss white.

Is it the 2K filler 540 white? I found this on a Dutch website, pricing seems about the same (€ 75 for 3 liters) as others for 0.75-1 liter.

What would you finish it with and how many layers of the 2K primer would you use?
