To a point, Marine Tex would be the way to go in order to finish from clear looking fiberglass even if you are going to put bottom paint on the boat.
To a point being small or short area's easily wiped with a squeege and sanded or water sanded and buffed for finish.
Yes gelcoat would be better than paint but Marine Tex is a good inbetween solution.
Better pictures of the damage might be the deciding factor.

Being there is that much damage, you will spend a fortune on Marine Tex.
Do like FERM said in the other thread.

I will fix the damage but besides that which type of tools do i need to have, like sand type and tools

Do you know of any special liquid to remove the bottom paint without needing to sand it, cause the gelcoat under the paint looks good and shiny and also if there is anything to make the gelcoat shine like new again without the need to paint, please let me know

Marine tex cost alot, i think i will use Gelcoat powder mixed with resin

An orbital sander like a 5 inch porta cable at lowes or HD would work fine for sanding. If it was me I would sand off the rest of the bottom paint and use a barrier coat type paint on the bottom. That way if you danaged the gel coat in anyway from sanding it will seal the fiberglass.

When I did mine I sanded and used resin and cloth to add to the bottom, this added back the material that was lost and sealed the bottom.
Sanded nice and since my boat was painted I just repainted.

I agree with above, you must seal it before you add gelcoat or anything else.

Good Luck

Did mine the same way as you MJ, resin and cloth. Been about 4 yrs now no problems. Made it smooth then added bottom paint. Can't tell at all.

People i started sanding the bottom paint with a 220grit sand!? is this ok?

Now after i finish removing all, which paint i need to buy? How many coats do i need to add and do i have to use a primer or something like a gelcoat barrier and where do buy these stuff?

Please if someone can give me exact detail of each product i need to buy or if there is an easy guide online let me know. thanks alot

Where i can find some cheap roll of plastic to put around the boat to stop the dust spreading around the houses?

You can use it to store the boat under when you're done, one of the portable canopys would work as a paint booth. The ones from Sams Club has sides, usually around $200.

Careful about the accumulation of fumes while you're in there, wouldn't suggest a fan either. Just spray a section, let the vapors settle then do another section.
