Hi Tail twister,
Well I don't think the gun I have will put out over 250*.
However the IRON worked on one part and although not smooth it did stick it to the wood where 90% of my covering problems are.
I tried the iron on the top setting but I can't get it to shrink or stick to the balsa.
I have a commercial gun where I can set the speed down and raise the temp.
I'll try that now.
This gun is used for BIG jobs like covering a boat up for the winter
Thanks for the post
