Finished with a nice, perfect poly glosscoat. I’ve heard you can start the rail line with #320 and then deck and bottom with #600. I always thought you had to start with #220 for almost everything to scratch thru the surface wax. I’d like to try the “timesaving” method and go #320 rails, then #600-1200 for everything. What do you think??
220,
320 grit to start with is just fine. I used to go to 400 grit next, then 600, and then polish. Going finer than 600 is not necessary, but is fun to do sometimes for the experience.
Actually, i go from 600 to 800 to 1200! Gets a real nice shine and then polish with Surfluster and McGuires is the finishing touch.
Depends how clean your gloss coat is…
If it’s super clean, you can sand with 600 and then rub and polish…
If it’s a little dirtspecked, maybe 4, then 600, then " " "…
If you’re good at sureforming clean lap lines, you can go right to 6 easily…light pressure, well used blade…
If you tear into the lap line with relish, you need 320…
Howzit 220, I scrap the gloss over lap on the rails with a razor blade then use 400 then 600, rails done. I start with 320 on the bottom to get a nice flat surface then 400, 600. For the deck I start with either 400 or just do 600 depending on how smooth it is, but they usually are real smooth and I think you are using the same mix that I do.After that it's Shurlustre for the rub out.Aloha,Kokua
I start with 320 on the rails but on flat surfaces takes too long to scratch the wax, so it’s 220 there. I like going to 1200 also. I’ve done 4 boards this week…my arms are tired. Here’s one of them. 5’4" retro fishy.
Howzit Liki, The trick to keep your sandpaper from loading up when scratching the wax is to not bear down with the grinder but to actually lift the grinder slightly to take it’s full weight off the board. I find that this makes my sand paper last longer.Aloha,Kokua
