Hello, i bought a new boat and need alitle help in the paint .

Hello,
I just bought a new boat here 's the photo.





It's made from wood covered with 6 a layer of fiberglass .
The Paint type 's gel coat .

I want to start to add a new look, i was thinking to spray the black Hull with gel coat metal flake, or change the black color to white color. Any suggest!

i have Gelcoat Equipment (Da sander - spray gun (HVLP) 1.8 ,1.4 .1.2mm nozzle etc... )

Also The seller give me ( 80 K.g of clear gel coat and 40 k.g of PVA and hardener, pigment black , white, red...etc )


I have a little idea about spray gelcoat supposed to be followed: correct me if I'm wrong!

1- sanding all the Hull with DA sander 80 or 120 grit
2-MEK with a cloth wiped and clean it's so good
3-Use a 1.8 nozzle for first two coats providing buildup
4-Final coat with a 1.2 nozzle and at a higher ratio of thinning (8% styrene thinning to gelcoat by vol)
5-Spraying PVA over gelcoat ( i waiting 24h before spraying PVA)
6- Wash the hull with water and soap (after 48h)
*There some Changes in the steps if i use metal flake:correct me if I'm wrong!
1- sanding all the Hull with DA sander 80 or 120 grit
2-MEK with a cloth wiped and clean it's so good
3-Use a 1.8 nozzle for first two coats providing buildup (with color i choose)
4-Mixing the clear gelcoat with metal flake as well
5-Use a1.4 nozzle for spraying the clear gelcoat it's mixing with metal flake
6- After 24h Use 1.2 nozzle for final coat it's clear gecloat
7-Spraying PVA over gelcoat ( i waiting 24h before spraying PVA)
8-Wash the hull with water and soap (after 48h)
When i was discuss with the seller he told me they spray gelcoat direct to the fiberglass without primer it's problem ?:!:
Thanks for every one taking the time to answer my questions and help me out

 

First thing you need to find out, is what kind of coating or coatings are on the hull now.

 

it's Clear gel coat. made in Taiwan it's come in barrel (100k.g= 27 Gallon)

 

Our 40 foot is an extremely dark blue color, it almost looks black, and scuffs from the bumpers in time have left noticeable marks. After 4 years (only 24 months moored) I am going to have to cut polish them out. My adjoining neighbors boat is white and has been in salt water maybe 8 years and there are not any visible scuff marks in his gelcoat and we use the same type of bumpers

Have you considered painting it instead as I believe paint will keep a higher gloss longer

 

The short answer is your plan for re-gelcoating isn't even close to being correct, so scrap it.

If you plan to actually do the work a more detailed method with a much higher chance of success can be supplied.

 

Gelcoat should be sprayed directly over the fiberglass or previous gelcoat. Primer is a really bad idea. The vendor doesn't seem to know the product he sells. Metal flake is very hard to apply and need a special gun to spray it. If you have gelcoat, and it is really strange that they used clear gelcoat, just sand it and spray on top. Use a product like Duratec to thin it and won't need to use any wax. With a 50% mix it sprays like an enamel and with a high gloss.
