i hope i'm not overindulging but here my po boy paint job and instructions for glass tank i got for $50 i was bored and wanted a project and it was certainly that
Put handful of drywall screws in tank and shake a lot this will score inside so caswells will stick and loosen any flakes etc
Fill tank with water to see where it leaks (water wont rust fiberglass!) mark leaks with chalk
Drain tank
Take JB weld tank weld stick and put it on leaking places wet your fingers it makes it much easier to press into cracks, pinholes and smooth out.
Fill tank again to make sure leaks gone even damp places need attention
Wash out tank with soapy water
Make sure tank is dry and pour in a pint of acetone slosh around and pour out.
Oh I make petcock hole plugs from shaved down wine corks you can plug filler neck with expanding plug for plastic pipes from lowes
With tank totally dry inside (you can use vacuum cleaner hose on exhaust to blow warm air in) Mix the caswells and pour ALL of it in and plug neck
Slowly turn tank every which a way over and over and over to coat inside
Unplug neck Pour out the left over caswells there wont be much
Pull out wine corks and make sure petcock threads are clear
Paint
Scuff the gelcoat with 600 wet or dry paint wont stick to gelcoat it’s too slick
Wipe clean with something like simple green and paper towels
Spray several coats rustoleum high build filler primer and let dry overnight
Sand primer with #600 with plenty of water til its smooth
Wipe again
Spray several coats Duplicolor Universal Black and let dry for a couple of days
Wet sand with #600 and 1000 and plenty of water to remove orange peel (I had a lot)
Wipe and spray with clear I used duplicolors new 1K product it is (allegedly) gas resistant (there are youtube videos about it)
Let dry several days then sand with 1000 and 2000 with plenty of water and then rub with turtle wax rubbing then polishing stuff them Meguires liquid polish clear in red bottle
Stickers
I got mine from restoremoregraphics on ebay his name is gary he knows paint and bikes and stickers
WIPE AREA WHERE STICKERS GO WITH RUBBING ALCOHOL OR THEY WONT STICK!! I learned this the hard way the silicone in the rubbing compounds has to be wiped off
Wet sticker area with spray bottle with a drop of soap in the water
Spray the tank lightly and peel the backing off the sticker and spritz the sticker lightly
Place sticker and take a credit card wrapped in paper towel and squeegee water/bubbles/wrinkles out of sticker
Carefully peel off the sticker paper
That’s it !
