tool/products needed:

orbital sander with 150grit sandpaper

rotary tool (dremel or equivalent)

soldering iron

120 / 400 grit sheet sandpaper

scissors

carpet knife

exacto knife

card stock (you can use a 3 x 5 notecard or any stiff paper)

pencil or pen

sheet of ABS plastic (the sheet below is about 22in x 16in x 1/8in thick, cost less than $5. i bought it from a custom display cabinet maker. this will last forever.)


i will be filling in one of the missing pieces off my rear cowl just below the mounting tab on the left.




let's begin, shall we*


1. trace an outline of missing area using cardstock.


2. cut out piece and place it on ABS sheet.


3. use exacto knife to trace outline of piece in ABS.

4. cut piece out with the carpet knife. DO NOT use the exacto knife to cut ABS, the blade is thin and may break off, it may also break off in your hand*


5. use sander to scuff area around the missing piece on the fairing, so you're not welding paint.

6. match it to the fairing. it doesn't have to be perfect.


7. use soldering iron and tack ABS piece into place. make a deep groove along the seams. go about 1/2-2/3 of the way through. use the soldering iron to fill in the groove and smooth it out as you go. weld a little outside the break to get a strong bond. let it cool for about 10mins. it should look like this.


8. do the inside as well for a stronger bond. use soldering iron to smooth the inside if you want but it's not neccessary.


9. use sander to knock of the high stuff.

10. use rotary tool to make edge flush.

11. use 120 and 400 by hand to blend in and smooth with surrounding area. now you're ready for primer/paint.


smooth as a gravy sammich*

post any questions/comments you may have.

Ali....thanks a bunch for posting this up. I hope this is placed as a sticky (I didn't check initially), but this kind of info is always welcome!!! I'm definitely going to have to try this sometime soon!

A couple of questions...what type of soldering iron did you use? Just the "straight iron" or a soldering gun? Any certain type of wattage needed?

Thanks again!

? I noticed some spidering starting, how is that handled.. I know that you repair is def going to slow it down, but exp tells me that it continues to spread.. Is there a small trick to incorporate to take care of that problem while making the repair??

i use a regular old soldering gun. no certain wattage needed, just the kind that will get hot and melt plastic

spidering is just the clearcoat cracking. once you start sandong it'll smooth out.

i used abs cement to repair some cracks in my side fairings, but over time, i don't think it will hold up as well as this method would

i used ABS cement when i first got into repairing plastics. it's good for filling in small cracks but when you have pieces that are separated then it gets messy. i find it hard to sand too.
