how do i fix soft spots on my long board surfboard?
my long board has soft spots on the top of the board, now i know im gona have to make a small cut into the board to fill in the soft spots, what is the best way to go about cutting into the board, what material do i use to fill in the soft spots, and how do i seel the hole that ill need to cut back up?
You may have a big problem with 'soft spots" If you can squeeze these spots, and they are 'spongy' you are probably have some water rot in the phone. Cut the glass out with a Dremel circular saw and cut out all of the water logged foam. Then using some scarp foam, cut it to fill the holes, and use the foam dust to fill int he cracks, the carefully re-glass the surface. If you are a fair hand at fiberglass work, you should have no problem. But, if you have no clue what I am talking about, the best thing to do ist take your board to a shop that has a good ding man,. and pay to get it made right. Word of warning, if it is a popout, you may be wasting your time. save up for a new board. Third world country popouts (China Boards) are usually made with substandard materials and notorious for passing water and delaminating.

Before you even think about surfing, there are some things you should understand. Surfing is an ocean sport, that should only be practiced by persons who are already competent ocean swimmers. Swimming in a pool is neat, but it's not ocean swimming, with undertows, rip tides and sometimes BIG waves. I have seen lots of great pool swimmers get rescued. So, my first tip on how to surf is to be at home in the ocean.There are way too many dangerous people in the water now. They are a danger to themselves and other surfers, don't join their ranks. We don't know too much about you. Maybe you already have the ocean skills.
Lessons are the best way to start. Lessons can come from a professional instructor, or surfing family members or experienced surfing friends. You have to learn surf etiquette (so the experienced surfers in the line up don't want to drown you), how to paddle and take off on a wave, and how to ride a wave. The last thing experienced surfers want is for inexperienced people to just grab a board, rush into the surf and get in our way. Lessons shorten the learning curve significantly. And they help keep ignorant, un-prepared kooks out of the water and out of the way of more experienced surfers. .
Beginners should take advantage of renting boards and wetsuits while taking lessons. If it turns out you don't like surfing, you haven't wasted a whole lot of money on gear that you are not going to use. When you are ready to buy, don't waste your time on line, go to a good local surf shop to discuss your size (weight is import, height isn't), skill level and local wave conditions. After 45 years of surfing, I still get my surfboard buying advice from good local shops in the places where i surf. A surf shop is also the best place to find information on instructors.
