1st time bottom paint hull. 98 explorer 215. Hull is in perfect condition what's best way to go about it ? Materials to use ? Products? Was thinking interlux which one ? Thanks.

By painting do you mean anti -fouling?
If so, then yes you will need to barrier coat it, with a epoxy fit for purpose. The whole idea of the barrier coat is to stop water permeating the gel coat and polyester leading to blisters etc. You need to make sure the area to be painted is properly prepped. There is a ton of info on Youtube. Start here. https://www.youtube.com/watch?v=YnXMI0-0FCM
I use Pettit Hydrocoat for the anti-foul paint. Main reason being its water based, easy to work with and can be re-applied season to season over itself, and it works.
Hope that helps.

The question is will the boat be kept in the water all the time or will it be trailerd? If it comes out on a trailer now and then some bottom paints will not work after being out of the water for a while. There are hard ablative types of paint that wear off with time that are made specifically for trailered boats.
I believe 98 they were using either a isophalic or vinylester resins in the hull so blisters should not be an issue, however if the boat is left in the water all the time a epoxy barrier coat is not a bad idea.

I am planning on getting a slip for the first time this year the boat will be in the water from may till November ( not as lucky as you Florida guys cold winters ). As far as barrier coat I did reasearch and interlux interprotect is sand and 5 coats and 2 coats of bottom paint but I thought that was if you had blistering and local guy I talked to said I could do a no sand system from interlux ( just clean and use 3m abrasive pads and interlux fiberglass surface prep) with 1 coat of interprotect 2000e and 2 coats of bottom paint anti foul so not sure which way to go ???

Ok I am really not educated in the types of fiberglass but it sounds like a good thing.

So 1 coat as a primer works ??

May to Nov I think you need to barrier coat it. This is the loose procedure. Wipe down with acetone (removes mold release & contaminants), sand, wipe down again & mask, apply barrier coat x 5 or so, 2 coats Anti-Foul. The reason I use Pettit Hydrocoat is that it can be recoated over itself season after season, it's water based and it works in New England. There are no short cuts for a proper job. My $0.05.

I just did a few coats of hyrdocoat on my 170. Like wooden eye, I love the ease of application with a water based bottom paint. Have no performance results yet of course....but will let ya know. We spent a good 6 hours sanding thoroughly with 80 grit to get most of the 3 existing layers of paint off. All about the prep of course. My boat is in Salem MA waters from may until October.
