The resist will not prevent being able to solder the board. I don't remove the resist before soldering, I using positive resist.

A long time ago I used the Tin, if I soldered the board soon after the Tinning process it soldered fine but if I did not solder it soon after the Tinning I had problems with solderability.

I decided it really was not needed to Tin the board, at first would leave the resist on the board till I was ready to load the board, then to protect the copper I spray it with clear Laquer. Now I do not clean off the resist, load and solder the board then seal it with the clear laquer.
