Interesting little project. I'll give a few answers for to chew on. I'm sure someone else will add more information. Some may agree, some may disagree, some may come up with some new stuff. Continue to investigate and use common sense. I haven't used any carbon fiber yet, but I understand there are certain precautions one needs to take with it. I will soon be learning because I have many projects coming up where it will be needed. Use the search feature on this site to find comments about different epoxy formulations.

: My problems have been.

: #1 Fish Eye's.
Usually caused by some kind of contamination such as oil. Might even be a little blush that's not getting cleaned off. If you are using an epoxy that will blush (and even if you're not) it's a good idea to sand and wash it off very good before applying the next coat (or apply while green).

: #2 Spots in the clear resin.
Could be the same thing as above. Might also be airborn dust, mites, motes, bugs, flys, etc. Really depends on what the spots look like. Not a problem if you can sand them off nicely before you apply the varnish, or clearcoat with uv protection.

: #3 Long dry times.
All formulas of epoxies have different curing times....and they can be formulated for temperature, location, curing characteristics, etc. I know nothing about Tap. Most epoxies are formulated and distributed by...say...epoxy "chefs". There are really not many companies that actually make epoxy ingredients. Several distributers may actually be buying the same ingredients and then formulating their particular "epoxy". You simply search around and investigate until you find an epoxy you like...then use it.

: #4 The resin has a weird greesey finish?
This is blush. Blushless and regular epoxy are actually two different formulations. A lot of the blush has to do with the curing agent. If you don't recoat while the epoxy is still green you'll have to clean that off. You'll have to do it at the end regardless. After scraping and sanding I wash with warm water. Some people use warm, soapy water...but then you have to make sure you get the soap off. 6 of one...half a dozen of another. I prefer to use blushless epoxy and still take precautions as though it is an epoxy that will blush.
: Thanks For any help you can give me
