Any advice, It’s my first shape and I hotcoated thinking the laps would blend in, but obviously I didn’t sand them enough. Does anybody have any advice, as I plan to sand then down through the hotcoat, and apply a second hotcoat ? any issues ? I dont have a big powerful sander just a little B&D orbital, which is why I probably gave up sanding earlier than I should have hoping that the hotcoat would cover a multitude.
If you know that shaping is something that you would like to continue doing, go get a 7" sander/polisher. I use a Makita. The right tools make all the difference. You’ll use it to sand hot coats, gloss coats, and to rub out compund and eventually polish the board all with the same sander. a small orbital sander will not cut it!!! So you will definitely be happier with the right tool. If not, you can get 36 grit sanding discs for your orbital. It will just take a LONG time. Also for down the road, mistakes are not covered up with successive stages of glassing. The cleaner the lay-up, the cleaner the hot coat, the cleaner the hot coat, the less sanding you’ll need to do, which will lead to an easier time glossing. But you probably have figured this out by now. Drew
If the bumps are in the lam then you will differently be sanding into the weave. Before you start sanding, coat your arms with baby powered…If you don,t, your find out why tomorrow! In the future, try to get each step as close to perfect as you can…use good tools, take your time, it will turn out so/so then after about ten years it will look good!
IIn the future when doing your laps sand them first using one of the hard sanding disks available at home depot, I forget exactly what they are called they are like 4 inches in diameter with a one inch hole in the center, use the red ones. geta small cup of acetone and cut that sanding disc into 4 pieces and set it in the acetone switching off when one gets dirty sand your laps, the acetone will help soften and blend, works great and you wont see your laps at all which is usually an issue with glassing newbies. http://paradoxdistribution.com
