many years ago i lived in phoenix ariz and hand made remote control boat hulls in the 6 to eight foot long size.
i got all my supplies at a very small supplier and he showed me a lot of fiberglass tricks.
at the time i guess i thought all fiberglass supliers were all this smart .[whoops] and so lost his business name.
now im in missouri and none of my family can find him.[please post here if you can]
what we all need to find is a WAX FREE POLYESTER ROSIEN.when using wax free life gets sooo easy there is no sanding between coats and this stuff stays sticky forever, allowing years to put down the next layer dry,peel off and stick until you have it just right and then using a roller to saturate the cloth with wax rosein or wax free.
wax free rosein can be final cured out with a light
coating of liquid car wax and is as stong as standard.
now here in missouri i have been to 5 diffrent fiberglass suppliers and they all look at me as if i were crazy when i ask for wax free.
i will admit this is not an absolute need when doing glasswork but i will tell you once you have used this you will never go back simply because of the ability to have as much time as you want to get everything perfect before the next step.
if you have ever had to sand out one wrinkle or had one delamination failure between layers you know what i mean.
another subject is ppl worrying about seeing light
through the camper shell,i know when glass is put over wood properly it is very hard to tell it is there all you see is the wood.
if you see cloth that is a weak spot either it did not adhere to the wood or sucessive layers did not adhear to each other this is most often caused by not fully saturating the cloth or not carefully sanding off the wax between layers.
now with this said do not let me make you think glass is hard or complicated it is realy easy.
my first boat made this way once came out of the water and hit a tree at 30? plus? mph.
3 hp 2 cycle motors make a lot of vibration the hull is now 15? years old and the guy i gave it to still uses it several times each year.
realise i had no help and didnt have a clue about boats or fiberglass.
so even bad glass can be strong just practice first any time you are learning and when your practice piece looks good take a hammer to it tear it up[try not to cry] you will learn so much from breaking it put it in a vise and try to use leverage to see if you can break it,if you cant get a strong young man you all know the guy hes the one who tears up everthing he touches.
life is a journey knowledge is the goal.
have fun jim
