tried doing a little powder coating tonight. it was just a junk motorcycle fender. we baked it at 375 for 20 minutes (you tube instruction) anways the fender came out like we krinkle coated it, was not smooth at all.why ? also when spraying the powder it did not seem to really cling to the fender, had to put it on thick.does anyone have any pointers? we are gonna try doing some pulleys and old valve covers to get some exp.
