Alternate exterior plastic parts repair

[IPM]

I bought and used the cheap plastic welder from harbor freight. I used it to repair the plastic bumper surrounds on my '81 motorhome which were badly damaged including missing chunks.
The rods which came with the welder were not useful but I discovered that plastic caps from spray cans(paint, bug, lube,etc) melt, stick, and fuse well. Add excess "cap" plastic and then remove down close to original with very rough grit. Switch to 80 grit and finer as you sand flush. Use autobody puddy to fill in dips, small imperfections, and then body glazing compound for pin holes. It helps to prime paint and sand several times to get best surface smoothness. Tool box grey, spray can paint, from sears matches original color well for final coat.

Just thought I'd pass the tip on for a cheap, effective repair.

Old milk cartons are also useful for plastic welding, I used this on my black water tank, and had great success.

Thanks for the information here. I've been fretting over exactly this repair and now see a course of action that doesn't involve bondo and tiger hair.
Thanks again!
