Hi ya Boxer
Don't be too hard on yourself about making mistakes - I don't think there is anyone on this Forum or anywhere - who can honestly put their hand on their heart and say they have never made a mistake whilst making a model of any description.
To give you an inside look today
this is how my story goes - in the process of drawing out on a 4 x 2 piece of plywood - a keel and frames for the next build of mine - discovered that I had drawn them out at the wrong spacing on the keel. So, instead of rubbing out I thought I would just turn the sheet of plywood over and recommence drawing - that's another day and a half of drawing - turning the sheet over - I wiped out the ceiling light which has a glass bowl on it - so I now need to replace that. Had to spend all morning cleaning the broken glass up from my room.
Also I kicked over the cat's drinking water soaking the carpet with at least 2 pints of watta. So there you go.
Right, to get back to your build - really - ideally - before you put the tissue and fibre glass on the hull - you should have filled in with car body filler P38 - & then sanded it smooth. But makes no odds, you have glassed over it now - but, what you can o is just fill all the gaps and bumps with card body filler and then sand. If you sand through to the timber again, give it another quick coat of resin and hardener mixed - obviously when that dries off - use wet n dry to finish off.
Then, you can put your fixtures or fittings in such as rudders and prop tubes or what I tend to do is give the hull a spray with grey undercoat and this shows up any imperfections.
I go on to fit the rudders & etc.
I tend to fit the prop tubes in first along with the motors and when I am happy with that, I will then fit the rudders and servos.
