Keep operating upwards through the pads, perpetually checking for scratches from the previous pad. By the time you rise up to the 2000 and 4000 grit pads, you must be ready to see your own reflection within the fibreglass chopped strand mat. Once you have got smoothened it all out with the 4000 grit pad, it is time for a visit to the motor vehicle store. develop some automobile polish, preferrably the kind designed to be used with associate orbital grinder. Get a sharpening pad for your grinder, and polish like thunder. Then apply a hand polish per the directions on the bottle. At now, your end ought to be scratch-free, and mirror-like. If you wish, wax this end, like a car.

Now what if you would like to form these wild shapes? initial, you wish to grasp what the top result can seem like. It helps alot if you have got the power to check things like this in your head. If not, maybe you'll be able to draw it, or have somebody draw it for you. Then, you wish a base to start construction on. as an example, say you needed to feature many curves to your dashboard. ranging from scratch would be troublesome, however it is simple to feature on. begin by taking the dashboard, and deciding what quantity material you wish to feature. anyplace wherever you'll be raising the surface by quite regarding 1/2", you need to build it up with foam. Get construction grade ployurethan two-part foam. this is often on the market during a spray box, that contains 2 cans. don't use increasing foam on the market from the hardware store unless you completely need to. increasing foam leaves immense bubbles within the within the froth. Spray the froth over the areas you want to lift, add a lot of foam than you propose to lift the structure. permit it to dry, and so form with a file/kitchen knife/sandpaper. form it dead set the required style, and provides it a coat of paint. Bondo can eat away at foam, thus you're making a barrier between the froth and bondo. Add regarding 2-3 coats of paint, to form certain all the micro-holes square measure crammed in.

Now, apply bondo generously. Shaping as you accompany the bondo. With bondo, it is best to figure with tiny amounts at a time, because it cures very quick. Build up skinny layers, shaping them with a spatula to induce the required form and flow of the top product. Once you have got engineered your form, use a cheeze-grater (a file, that appears remarkably sort of a cheeze-grater, not associate actual grater) to form the bondo to the required form. it is best to figure with the bondo whereas it's exhausting, however not totally cured, because it can virtually work like exhausting cheeze, permitting you to tkae off alot of fabric terribly quickly. permit it to dry utterly, and so sand it down with a 40-60 grit to form.
