^^I've been asked about what I use for filler and this is the stuff. It's a product we use in the autobody trade to repair plastic bumpers. It dries fast, has two stages of workability, sands easily, feather edges without leaving halos, and will stick to anything. You can find it on Ebay or any autobody supply store. It's called Fuzor plastic repair -114. ^^ Ever have some ungodly gap caused by poor measurement? Well, here's how you can fix it quickly and easily. ^^Tape off your details first. ^^Load er up with the plastic repair. ^^Leave it to set up for 2 minutes and carve the excess with a knife. ^^Don't take off too much. ^^And once sanded, it should look like this. You can sand it in any grit so long as you finish it with 320. (unless you use a high build primer, then 180 will do. Here's an easy and fast way to tie in panels. ^^Begin by taping off the areas that need to stay clean. ^^Jamb the filler in there then...... ^^Peel the tape off as shown. It's important to peel it over itself as it cuts a nice sharp line. Afterwards, just shave the filler down as shown above and sand it smooth.
