should I bake the flowcoat?? - Page 2

don 't think I'll get instructions as such.

Any guesstimate on the drying time for a 3% catalyst mix at 20 degrees?

If I did it in an evening after work, how long would it need to wait in the oven until I could take it out and drive home??

John, don't expect to get the nice gel-coat finish by re-coating with flo-coat! It cures in a matt finish, shows up brush strokes and is very hard to buff up.

You can sand the flow coat and then polish it but it'll take you ages to get a nice chiny finish!

if its not done right here is the consequence,,,,,,,,,,,,,,

eek! Hope mine doesn't end up looking kike that. Any idea what wasn't done properly?

Did mine last night in my mate's workshop - not quite the spray booth, but still warm enough.

It certainly isn't fun stuff to work with, a cross between rolling paint and spreading margarine! THe end result doesn't look too bad though it does show up roller marks (as a previous poster said), but i had ground down the whole area with 400 grade discs and then cleaned thoroughly with acetone. Hopefully it will stick? It's certainly set hard enough. Will just cover the 'not so nice bits' with some tread mats.

Now just the console and engine to fit....easy....

That looks like bad sub surface preparation - underlying surfaces were not sufficiently "keyed" in with abrasives or were far too dirty when the flo - coat was applied

to much wax i reckon who knows
.floor looked well abraded after removal, either that or it got damp prior to curing,

Hmmm that looks a lot like what I found lurking under the engine on mine. I've decided while the horses are off the transom to just do it properly & have stripped all fittings & fixtures, removed the antifoul etc etc and now wonder if the bottom layer of paint was actually flowcoat applied with the similar surface preparation as the toobs didn't get before they were painted......

So, the question - How easy is it to apply vertically? I assume no worse than applying "standard" gelcoat?
