My son lives at the beach and purchased an old 70's Yamaha G1 to haul his surf boards to the beach.
Naturally I had to get involved.  Never worked with fiberglass  body filler, of automotive paint before.  Other than the sanding it's kinda fun.  I'm leaving it up to him to put the body back on and wire the lights and turn signals.

Cool deal.  Not enough car-related projects on FOG for me.  What sanders are you using?  Any lessons learned or advice?  No detail is too small for my interest.

Oh, right, great work!

Cheers - Gary

Sanders:  A little CTS150, a bit of RO-90, a lot of arm-n-hand sander.  There isn't a straight line of a flat panel ANYWHERE.

This made lining up the switches, speakers, turn signals very very difficult.  I tried everything.  Painter's tape,  a level, calipers, a combo square to get me in the neighborhood of where a hole will be drilled. 

Working with fiberglass is pretty easy.  Just paint on some resin, lay on a sheet of glass cloth, and repeat 3 times.  At least 3 layers worked for me.  That fixed up the cracks, reinforced vulnerable areas, and provided a base for filling holes.  When it dries the edges of the cloth will do a number on your skin.

I used Bondo resin and glass mat.  Bondo "Glass" filler. (wow this is good) and Bondo putty.  Then I primed with Eastwood "Contour" primer.  It has polyester in the paint and fills small imperfections nicely.  Next I learned about Top Coat (the color) paint.  There is a Single Stage and a Two Stage top coat.   Basically a single stage dries with a gloss.  Two stage is separate.  Most everything needs a catalyst mixed in the paint.  What I found really cool is flash point of the paint.   Say it’s 90 minutes.  After that you can apply another coat without sanding.  This includes any clear coat.   If you wait 18 hours you have to scuff sand everything.  Anyway 3 coats in a day!  Since auto paint is quite pricey I went with Summit Racing Single Stage  It was a lot less than most everything else I looked at.  Even though I used a single stage I purchased a clear coat.  KBS-Coatings Diamond Clear.  No catalyst, water clear, goes on after the flash point of the top coat and it dries  very hard.

I'm quite concerned about that head unit ... I'm sure you could engineer a stylish valve amp and retro tuner into that rig [big grin]

Looking forward to more pics.

It is now time to engineer a surf board rack.
Grant wants to design and build one with his roommate, but when I heard the word PVC my overbearing instincts kicked in.  He's thinking running board orientation with hooks.  I though getting out of the cart  might be a challenge, then I remembered he's 6'6"

This could work if it's made out of EMT.  Going overhead is problematic.  A structure needs support struts and it must be tied into steel.  There's the Bimini design but you still have structure to deal with.  Lastly there is a cantilevered behind the seats.  The boards stick up out the back.  But there is only 2' from the seat back to the end of the cart and his collection of boards runs from 5' to 7'

I think I need to suck it up and let him do it.   Aaaarrrgh.  He's probably only put in 6 screws in 24 years.  [scared]
He's a nuclear engineer,  hopefully his roommate is a mechanical engineer.  There's hope
