I forgot to post on this too…been very busy.
Only use Epoxy type resin for this use.
Grind away any cracks to a “V” so the reinforcements has a chance to flow in and bond the repair.
Clean it with Acetone to get rid of any dust and let it fully dry.
You could use a wet lay up with high shrink wrapping from Dunstone which I think Airtech is a dealer for Dunstone. Dunstone donated several rolls to my class and we have just started to use it.
What you do is lay out how much CF cloth you need to make at lest 2x complete wraps and the ends butts together, weigh the cloth (this is to get the same wiegh in resin to ge a 50% to 50% ratio), mix up the same weigh in the epoxy resin (plus a little extra too) and add the hardener to the correct % listed.
Next wet out the cloth on some newspaper or PE sheet to get it fully wet out. Take it and wrap it onto the tube, try holding the last end and use the Dunstone HS wrap (outside down) and start to wrap it (you can use masking tape or better yet, flash break tape to hold and secure it) but over lap 50% each wrap around.
At the end, again hold the wrapping as tight as you can and tape it off. I’d also reverse the direction and repeat the process.
Now, take a heat gun (or place in an oven) and apply heat to shrink the tape and it will apply 2500 psi when it is fully shrunk.
Let it fully cure (even for a day or two) and remove the tapes. Now just litely sand with very fine sand paper and clear coat the whole frame.
