My try using tape over jb was for a deep gouge in the side of my carbon foil board, for deep scratches on a wing I just clean out and prep with a tiny sharp end screwdriver to get a good key for the jb,Kamikuza wrote: ↑Sat Aug 10, 2019 1:57 amCheers guys.
How big a repair were you doing?Foil wrote: ↑Fri Aug 09, 2019 6:31 pmI have only tried the clear tape trick once, it failed for me as it failed to cure correctly,
maybe leaving it for 2 days, not one day like I did may work, fingers crossed.
I've looked again at mine, and what I thought was a massive hole is really just a deep scratch -- if I tried to add any glass, it'd be too thick.
mix a tiny bit of jb,
push it neatly into the scratch with again a tiny screwdriver being careful not to get any outside the scratch area,
then using a clean and new stanley knife blade, hold it at say 45deg, press it gently down on the unscratched surface just before the repair line and push it slowly along the surface, following the direction of the scratch line,
lift off after the end and wipe the blade clean against a stiff flexible bit of plastic,
inspect the repair, if you need a bit more jb then dib that on neatly with the tiny screwdriver end and repeat the smooth blade pass,
you end up with a near perfect glassy finish with no excess jb, or if you get Jb on the area around the scratch then use a damp clean cloth and rub it off, this will save time and further risk of damage when you come to fine sand the line down when dry,using 800 wet paper, any tiny air holes can be fixed using the super glue trick,
one tip using superglue it to buy the little bottles that have the tiny brush inside to apply the tiny amounts you need,
and it's way easier to deposit the baking powder off the end of a tiny plastic blade and tap it over the wet glue, which delivers the fine power more accurately than ever using your fingers.fingers do work but can be messy.
