Custom fiberglass without a mold (2)

Lets begin with the last one, the piano end. this can be typically the goal of most fibreglass work. you'll be able to simply paint one thing to attain this look, however it needs a little of talent with a paintgun, and it doesn't offer off the deep look a fibreglass end can, unless you're extraordinarily smart with paint. For a piano end, what you actually wish to try to to, is barely use the rosin. Get some finishing rosin, preferrably the things wont to create surfboards, immoderate high gloss. Paint it on to a superbly sleek surface. this can be key, any imperfections within the surface are increased by the fibreglass. combine the fibreglass chopped strand mat with a coloring agent, and use alot, to convey a awfully opaque end. Paint it on thick, and canopy everything equally. If you would like to, do a second coat before the primary coat loses it's stickyness. I counsel between 3-5 coats. On the ultimate coat, skinny the rosin with solvent, this may facilitate fill in a number of the comb lines.

After natural process utterly (2-3 days) begin sanding. increasingly sand with increasinjg grains of sandpaper. begin out with a high grain, like 400, and sand the full surface. As you sand, it'll impede the raised areas, departure the pits and valleys a awfully high gloss, creating them simply visible. If potential, sand these raised areas all the way down to very cheap points within the pits. you will need to use a coarser paper to attain this. once sanding, allways conceive to use a random orbital power tool, the scratch patterns of different sanders, or hand sanding aren't desireable. If you have been sanding a cruved surface, you can use a foam backing pad for your power tool, to permit it to hide the snaky areas. you'll be able to get foam backing pads up to 1" in thickness. this may enable you to try to to some pretty wild curves.

Once you have got the full space sanded to the same uninteresting look and smoothness, you must then work your method duplicate to the four hundred grit paper. Purchase some "Abrasol" pads for your power tool. These area unit foam pads obtainable in grits from a hundred and eighty to 4000, specifically created for making ultra-fine finishes. They work best once used with water. Clean the surface of your box with a tack textile to induce all the mud off. Then, employing a squirt bottle assault mist, utterly soak the box. Use the abrasol pad on your random orbit power tool, making sure the pad is allways rotating at a high rate of speed. If it slows down, squirt additional water on the realm. perpetually sand and squirt. The a hundred and eighty pad ought to be wont to begin (following the four hundred grit paper). this may leave a shine to the fibreglass. you must examine rigorously for deep scratches, and work them out with the abrasol pad if in the slightest degree potential. The abrasol is additional of a power tool than a power tool, it will take away scratches, however won't impede into material. once sanding with abrasol, lubrication is that the key, thus use lots of water.
