Hull Truing

[toyotatruckin]

bondo with hair will be extremely hard to work with, wouldn't suggest using it to blue-print the bottom of a hull with, if your building up an area like a sponson tip strakes ride surfaces etc id use it, for blue printing bottoms regular bondo will work fine, good finishing putty auto-zone may not carry but it's best to use (and expensive 25-30 bucks and up around here), if you need and the bondo is thicker than you want you can thin bondo down with fiberglass resin (both are poly) cream hardener will still work like it is supposed to BUT it will make it harder to sand!

What is blue-printing the bottom of a hull?

What is blue-printing the bottom of a hull?

Another way of saying what the pictures show. Truing the bottom. Its called "Blueprinting"

I have some fiberglass balloons. Could i mix that in with some 30 min epoxy to fill and sharpen the edges?

[toyotatruckin]

yes you can use micro-balloons, and tiqueman said it easiest about blueprinting, truing up the surfaces making sure everything is flat that should be and sharp where it needs to be and tuning the hull to make it run at its best (or trying to at least lol)

The thing is i dont have a card to order online and i am trying to find a local place to buy from. Apparently none of the stores here carry evercoat.

[toyotatruckin]

anyplace that sells automotive paint should have a finishing putty, napa, oreilly's,jarvis etc, hit the phone book and call around.

BINGO! I found the right stuff now. Thanks

[boaterkid333]

do you just roughen the sponson up a little so you dont have a shiny finish?
